I was outside, at the Salty Paws Saloon looking for a stray cat at about 10:00PM. I found one, her name was Rani. I begin talking to her, and I got the friendship meter about a quarter way full. I attempted to offer my friendship, however when I did so no animation occurred and Rani vanished instantly. I checked my Sims relationship bar and she was not on it. Is there at least an explanation for this? I really liked that cat.

When using the save, replace the Sims 4 file with this one. Continue playing as Wasabi Koi, and wait until 3:35 AM. The cat's relationship bar will then get deleted.

EDIT: After exiting without saving, and waiting at the same place at the same time ,after reloading the SIms 4, Rani did eventually re-appear. Sorry!

EDIT FOR THE EDIT: After loading in the Sims again, Rani did infact disappear again at 3:35. I have a video recording if anyone wants it, this refuses to post with the video attached. Sorry. I'll also copy the save if anyone wants to take a look. The glitch happens 100% in this save.

Could you please test if this happens on an unmodded game as well ?

Thanks crinrict! I tested the game with no mods, and the glitch is still occurring. The save of the game I'm using I've added as a link in the original post, as well as the video. Thank you!

Bit confused on your save. Rani ïs part of the Koi household in that save a bit different from the video ?
