@abs_clown_shoes Do you have mods or CC in your Mods folder? If so, do a "vanilla" test to see if a mod/CC is your problem: Drag the Mods folder to the desktop, delete the file called localthumbcache, open the game to test, and exit without saving.
I have had this happen with and without mods. I suspect that what is happening is, that if the focus Sim leaves the lot while the bed is in use, the In Use flag isn't cleared when the focus Sim returns. Instead, it isn't cleared until the assigned horse uses it again and wakes up while the focus Sim is on the lot. I have not, however, tested this, but it seems like a reasonable edge case that could cause it.
@richvh This seems to be correct! Both my horse beds couldn't be cleaned. One horse slept on it, i woke him up, he left and then i could clean that bed, yet not the other one. Thanks to this comment i figured i should try and it worked thank you!
