Since few patches I noticed some mobs don't spawn. After hours to explore worlds in creative mode, I saw only few like whales, skelewags, giant squids and comb jelly in ocean biome. On the lands I met just gelada monkeys, bisons, flutters and the new mobs of the 1.21.0. In the nether I could see just stradders, souls vultures and a lot of crimson mosquitoes !

I tested the mod in several configurations :

• With all my mods, like terralith, create..... and recommanded Forge version
• With only Alex's mobs, Citadel,Optifine and recommanded Forge version
• just Alex's mobs, Citadel and recommanded Forge version
• with the last version of Forge

in all those cases I have this issue.

Have you deleted the old config files of AM? I encountered this issue when updated 1.18.2 to 1.19.2, and after deleting the old config files, the new ones were automatically generated and everything went right.

Actually it was mentioned at the update log on CurseForge...

Oh ! It works ! Thanks !

Where can I find these config files?
