Board Thread:LotR Mod Technical Support/@comment-75.110.43.167-20181108154232

I have a custom modpack with over 300 mods, one of which is AntiIDConflict, which makes ID conflict crashes easier to read and fix with the use of text files detailing the conflicting and available IDs. The pack generally works well with no big issues, but when I add LotR (and Tinkers' Middle-Earth, if that's relevant), my game crashes with the following:

[net.minecraft.client.Minecraft:func_71377_b:349]: Minecraft Crash Report // Surprise! Haha. Well, this is awkward.

What's especially odd is that normally it would format it as Biome (biome.name), Biome (biome.name) when there's a conflict. The conflicting Sky biomes are not causing this crash; that was done intentionally. So, the fact that one biome can conflict with itself suggests something rather fishy is going on here. Since neither Vanilla nor LotR let you change biome IDs, I decided to post this here. After I post this I'll try removing Tinkers' Middle-Earth just in case that's the problem. I can post the full crash report if necessary.
