Description of the problem

How to reproduce:

Basically, I've built a thing in another world, and then tried to bring it to my main one.
1: Build the thing
2: Exit world
3: Replace the DIM20 folder in the Real World with the ones from the Build World
4: Launch the world
5: Try to TP to the location of the build
6: ???
7: Crash with Stack Overflow

Expected result:

Nothing to crash, me to be able to play.

Actual result:

The world crashes.

The building is on a Laputa Shard-generated floating island, and uses LittleTiles.

Addendum:

Yes, I know that it's an extremely specific and unlikely issue. But it's still an infuriatingly weird crash, and I have no idea at all what could've produced it, especially since the original world's still fine, AND the Betweenlands in general are fine as well, it only crashes after I get to the building.

Try the build without the little tiles if you can, then move the folder.

Still the same crash.

If I remember correctly you can't always simply copy a dimension's world into another world's folder because the block mappings might be different (e.g. if not exactly the same mods were used when creating or playing on the two worlds), and incorrect block mappings can cause exactly such a StackOverflowError.
