I noticed that. The bike was bought used, and it came to me like that. I thought the cup might be cross-threaded as well.
As a quick temporary fix, I'm considering removing the fixed cup, screwing it back in, and seeing how it goes. For a permanent solution, I want to replace the entire bottom bracket.
Do you have any recommendations for a bottom bracket that would fit, if and when I am getting a new bottom bracket? It's a 1990 Schwinn World Sport, FYI.

I don't think you'll be that lucky since it's obviously been ran too loose for too long.
I think it has a pair of cage bearings, with 9 balls in one and a total of 18 balls overall.
