I have found out that one BiomeID and a few potionIDs are used two times:
E. g.:
23 is asked by: JungleEdge (net.minecraft.world.biome.BiomeGenJungle), Caves (enviromine.world.biomes.BiomeGenCaves)
I found this out because befor I play a MP I install the mod AntiIDConflict. It scans in the IDs for Biomes, Entities, Dimensions, Enchantments and Potions and on default crashes the client to let you know you have some ID conflicts. Also it has a file in it to show you which IDs are free to use so that you can be sure that next time no conflict will appear :)
Hey,

The full conflicting Items can be found here: https://pastebin.com/w2BnVT69
I should mention to remove AntiIDConflict after resolving all conflitcting IDs because it is then no longer required.
I hope that this will help since the mod is in my eye's a must have to solve ID conflicts for 1.7.10
