[14e Steam] Cow pregnant despite not having a bull

[neverdie]

So, i have one cow that got pregnant over night, but i don't have a bull.
Have some Muffalos (cows and bulls), but I don't think crossbreeding is a thing?

Can provide savegame if needed (modded).

Edit: the cows movement is restrited to my base, so no bull from outside could be responsible. Don't think there's any bulls on the map anyways.

Animals can magically breed at a distance even through walls, so a wild animal can definitely be responsible (in which case it's Working As Designed).

This thread is for bugs in the base game ("vanilla") only.  I'll lock this thread for now.  If you believe the bug is related to a specific mod, please post in the mod's thread.  If you believe it's mods related, but aren't sure which one, post in the Mod Bugs subforum.  It's only a bug in vanilla if you have no mods running and there are never any bulls on the map.  (A bug could impregnate a cow and then leave the map or get killed, remember.)  In the case that it *is* a vanilla bug, PM me and I'll unlock this thread.
