I'm creating a modpack for myself in 1.7.10, (because that's where most mods were at their peak) and because of this I run into a lot of ID conflicts. Most of them are biome or entity conflicts because there are very few biome and entity ID spots compared to everything else, (I have not enough IDs and potion extension installed) and because modders didn't realize they didn't need to assign global IDs since 1.6 for some reason.
I know Just Enough IDs increases biome and entity IDs, but that's not available for 1.7.10, so if it's possible, maybe someone could find/make a backport of it for 1.7?
If that's not possible, is there any way to increase IDs for biomes or entity's? I'm not very fluent in coding language, so I might need a step by step tutorial.
If neither of those are possible, are there any other mods that can increase entity/biome IDs for 1.7? Thanks.
