As I was competing in the Finchwick cow fair, like any normal person, I registered my cow. However, I noticed my cow wasn't appearing around the shed I put her in. I was confused and checked in my inventory; turns out I now have two cows, one which was my actual cow's name and another called Spotted Cow (keep in mind that they are the same cow, same accessories, same friendship level). I checked on Reddit as well as here to see if people had the same problem and turns out most people do. I tried restarting my game, selling the shed, dragging my cow in a new one, basically everything logical. Something I tried (and I'm not sure if any of you also tried) but I got two sheds instead of one in hopes it would magically solve the problem. It didn't. However I noticed something odd when I was assigning the same cow to the two sheds; at one moment, one of them started having the "sleeping signs" (aka the Z). Turns out my game still counts the cow as in the shed but the shed doesn't count my cow in it, meaning I still have those two cows in my relationship panel and one in my inventory. For anyone wondering, I stayed for the whole event and even got my prizes. Have any of you solved this or know how to possibly solve it? (I don't want my cow to die in my Sim's pocket like everyone's-)

You can also see the two cows in my relationships panel (please don't mind my sim being a random plant sim)

In any case, thank you lots!
