Teaching is exhausting.
I fixed the age data persistence issue (with data from other saves or servers getting copied to your current world). I’d implemented a semi-hack -fix on the Age Data to make it consistent for the server worlds. Now I’ve hack-fixed that to make it clear that data when the world changes. 😛
The actual issue is with how such data is handled. I’d expected it to be consistent and stored once received, but Minecraft seems to like to create clones of it. I understand what’s going on and it’s reasonable, it just doesn’t work well for me. In lieu of implementing a better data tracking system this will have to do.
