My friends and I are playing a modified version of BMC4 and we're noticing stuff like passive mobs. (I think) like creatures/animals from Alex mobs, naturalist, let's do nature and even vanilla MC (sheep, cow, pigs, chickens, horses, donkeys) don't really spawn in, unlike the sea creatures and hostile monsters spawn in just fine and normal numbers.
Here is a mod list from a crash report: https://pastebin.ubuntu.com/p/K9vJxxx6n4/
Just a quick copy and paste of the mod list from an unrelated crash report
If anything please let me know if I should post pics of the mods from my mods folder
I want to know how to increase their spawn rate/amount and if there are any mods that are causing the scarce appearances of these mobs
