I have Uni, NL, OFB, Pets, and I just installed Seasons. That is when this problem started happening.
To be more specific, it crashes only when I try to view the "Decorations" --> "Miscellaneous" (the button with the three circles). I can select "View All" and see the first page of items, but as soon as I hit the arrow to go to the next page, I can only assume one of the items from the Misc. page is on the next page, and the game crashes again. I can view all other items in the Buy Catalog without problems, including all items under the Decorations tab, except for the ones under Misc.
I have removed my hacks folder; no effect, the game still crashed when I tried to view Miscellaneous Decorations.
I removed any folders containing custom furniture; game still crashed.
I have not yet removed the entire Downloads folder, but I did try removing any folder of custom content that may have affected the Buy Catalog in any way.
I have deleted the Groups.cache to no avail.
Basically, I have run out of solutions, but to no avail. I was hoping someone here might have an idea for me that I have not yet tried. My gameplay is not affected in any other way. This is the only problem I have encountered, in that one specific area, and while it doesn't destroy my ability to play the game, it is rather obnoxious.
The only thing I can think of is an uninstall/reinstall, but I wanted to post here and get opinions first.
