I'm playing on PS5 in the latest update. It's been a while since I've checked the ranks, but recently I noticed my rank for Museum is saying I need 251 donations to get to the new rank and says I've donated 185, however, I've actually donated 254. Even donating something new is not updating the count. Now I'm not sure if the ranks for other stuff are fine or bugged as well.

i think with every donation you get three points for the rank. i could be wrong, just a thought really
