NPC/Cows stuck underground, splashing water sounds

[vast pagoda]

I was able to see at my farm that a cow was stuck under the waterfall. There is also some kind of random building part under there. Then today i went to the town and I heard the same splashing sounds. There are no cows here so I am thinking it's an NPC however i am unable to see what it is. screenshots are of the cow under my farm

@vast pagoda do you have multiple barns?

no just one

Happens at mine quite regularly with the animals when I leave the farm randomly and get back when I have left them to be outside, gotta ring the bell to make them respawn

ooo next time it happens at my farm i will try ringing the bell to see if it's my cow that is stuck because i assumed it was just some random cow // update it worked
