i've seen crocodiles on plains multiple time i tried without other world gen or biome mods and crocs still spawn on plains

same happened to me. this one spawned on a Sierra Valley from Oh The Biomes You'll Go

they spawn in deserts too, i spawned in one and 2 crocodiles spawned right next to me.

I also have the same problem but with crocodiles there are emus, gazelles and kangaroos. They are always together and I have seen them in plains, deserts and savannas.

i've just seen crocodiles in snowy toundra.

Fixed in 1.12.0

a fix for this bug would be appreciated
