So Im playing on my own modpack, and figured out that after adding Alexs mobs rabbits doesnt spawn anymore. Any fix plox? :(

together with alexmobs comes a mod called citadel
change in the citadel config the "chunkGenSpawnModifier" from 1.0 to 2.0 (or higher depending on u other mobspawning mods)
this should spawn rabbits again tho they will still be rare (specially since alot of mobs tend to kill them like snakes in deserts)
