I fixed everything and there are no problems now :)

Hello gamers. I finally got around to fixing up this little project so now it shouldn't crash stupidly anymore. I had to sacrifice some aesthetic choices but at least now it is fully functional (I think. Please let me know if this error still occurs).

There are still some minor issues, like the items not displaying on the squares to the side. Still figuring out that one, I have a solution but it will be a bit tedious so we'll see.

Other than that, the game works and you can actually reliably play it now. A whole two months after publishing it. Very cool of me.
