Broken mod

[KinaAxian]

Hi again ! I decided to make a second topic for this because it's completely unrelated to the one I did earlier, but - so, there's this mod I made yeaaaars ago that's on the workshop : the thing is, a former friend of mine did most of the coding for me when I just did the basics and all the art. I loved to use this mod even if I didn't play as the character because it had custom items that would spawn ont he map too etc.

The thing is, I'm no longer friends with that person and my knowledge in coding is extremely minimal - I realized that after a few years without playing, this mod causes the game to crash constantly, and I have no idea why. Would someone be kind enough to look into the code and tell me why it suddenly stopped working ? ;w;
