Mystcraft for 1.4.6

Mystcraft build for 1.4.6 is up and ready! 🙂
Sorry for the general delay. Many thanks to cpw

This is primarily an update release.
Note that this does NOT contain the celestial mechanics or other thing which were streamed earlier. Check out the change log for what it DOES contain. 😛
Mostly this contains bug fixes. A few minor interaction changes, such as shift-click removal on stands and interacting with the receptacle.

To recap: there is only one download (found at the bottom of this post); This file is the universal install for client and server; it no longer goes in the jar.
Mystcraft now goes in the mods folder.

Download: [1.4.6] Mystcraft Universal

  1. Yes! Thank you so much for working through your vacation to get this done. Now my mod-list is complete!

  2. I’m sure I speak for many when I thank you for taking time out of the holiday season and getting an update out. Have a wonderful holiday!

  3. Yay! Thanks so much for the work you put into this. I don’t know how I could play minecraft without this mod.

      1. Had 474, server crashes every time player enters an Age… upgraded to latest, same thing…

        1. yes i think there is some more work needed to get it run properly. But its Holiday time so it is nice to get a version. I think i will keep the mod installed but disable all age related for now.

          1. forge 480 works just fine. Able to create worlds without problem. 481 breaks everything though.

          2. forge 471 crash (cause as stated some newer version is needed), latest forge- works fine (as of this comment 486)

  4. Thanks for all of your hard work, especially given that this is your holiday.

    We all appreciate your hard work 🙂

  5. Hey, thanks a lot, although I’ve found a bug -> I was trying to do automatic RP2 mystcraft portal station, but when I tried to use RP deployer with book on reptacle I got this:

    java.lang.ClassCastException: com.eloraam.redpower.machine.EntityPlayerFake cannot be cast to iq ( …, if needed, i can provide full log )

    Thanks 🙂

    1. I had the same problem You need to use tubes instead of a deployer that works for me 🙂

    2. I’ll have to take a look at that, but please note that the receptacle is a valid inventory and so you shouldn’t need a deployer.

  6. Hello,
    First of all, thanks for the superb mod.
    I noticed that if you use a notebook to create an age with symbols of Extrabiomes that are disabled in the Extrabiomes config. You will crash the server. I am not sure if this is the same with randomly created worlds.

    Maybe you need a check to see if the biomes acctually exist? 🙂

    Happy christmas, go get fed. :p

  7. Thanks for the hard work, great christmas present to the comminity. 😀 I found another bug, whenever you try to save and quit inside an age, it crashes.

    java.lang.IllegalArgumentException: Could not get provider type for dimension 2, does not exist


    This release requires the .474 version of forge. The **Recommended** release is currently .471, and the **Latest** is .481.

    To get things working properly, go to this link: and search for the build ending in .474.

    Also, just open the .zip, and dump the files into your minecraft.jar–it should overwrite just fine!

    I hope this saves someone all the trouble I went through checking all my other mods for compatibility! 😀

  9. Well, I just came to say Merry Christmas, but thanks for another release. Will try it after celebrations and when I feel like updating.

  10. I crash when try to use descriptive book… why? I’ve forge and other 41 mod… but I tried with only the forge and mystcraft and the result is the same… help! sorry for the bad language i’m italian…

  11. There seems to be major crash issues when pushing minecarts through Mystcraft portals. I tried it with a Railcraft tank cart, but I’ve heard it does the same with vanilla minecarts?

  12. I have a server running, and after a few tests I’ve determined that the server crashes every time an entity tries to go through a crystal portal. Players can go through, but it says that they have moved wrongly.

  13. Minecarts causes critical bug!

    Description: Exception ticking world entities
    java.lang.IndexOutOfBoundsException: Index: 368, Size: 368
    at java.util.ArrayList.rangeCheck(Unknown Source)
    at java.util.ArrayList.remove(Unknown Source)

    at in.h(

  14. You also can not send item trough portal into nether -Forge 486 minecraft 1.4.6
    No it is any item to other dimension.

    java.lang.IndexOutOfBoundsException: Index: 272, Size: 272
    at java.util.ArrayList.rangeCheck(Unknown Source)

    1. Minecraft has stopped running because it encountered a problem; Exception ticking world entities

      That same with forge 489 486 even 474 ! So i dont know where is problem .. I dont have problem send items in same dimension trough portal but to another dimension every time crash.. even I add chunk loader to other side but nothing

      1. And i have turned off some ore spawns like Copper from redpower2 and thermal expansion but in other dimensions.. this ores still are here

        1. Dense Ores generates other mod ores if they are registered to the ore dictionary.
          This will be addressed in the near future, with luck.

  15. I couldn’t find a note about this, and I’m averse to making random forum logins for one post, so here goes. Been playing FeedTheBeast beta on a local server, 1.4.2 version.

    I have a reasonably stable age with random explosions, 3 charge, flat and 3 dense ores, among mundane selections. I selected every element available, and made sure to avoid conflicts. I still ended up with three extra sky colors in the book after trying it, but they don’t seem to be causing corruption.

    The issue I’m having is this: I’ve mined down to bedrock and it’s perfectly flat. That’s fine. But when water flows on the bedrock… it sprouts holes!? The holes ONLY appear where water is in contact with the bedrock, and they don’t seem to be common there, but I haven’t had any other way for bedrock to be destroyed, and holes don’t form where there is no water.

    I just recently had a new downpour by accident, left it alone and the next visit to the age I found the bedrock perforated again, but only where water was on it.

    Weird. o.O

  16. Is this version of mystcraft safe to use? I herd that the 1.4.6 can mess up your world.
    Is this true?
