Without JEID, this mod adds a compass that lets you find and teleport to the closest specific biome you choose. With JEID, this compass is broken and finds/teleports you to the wrong biome.

I've also met this problem

I have the exact same issue. It says 'a mod does not support extended id's' and crashes when I try to locate biomes. I however have been unable to pin down any particular mod that does not support extended id's it seems to give this message whenever I have enough biomes to need JEID installed. I have tried different combinations of biome/dimension mods and always get the same problem.
