So I made a mod to add a pouch that holds items and allows for one of the items to be selected and used. It works perfectly in single player. However, as the title says, it crashes a server that hosts it. I would really appreciate help on the subject. I document all my code and try to make the variable names as descriptive as possible, though I lack in comments.

Per request, I can explain any section of the code and what it does.
Crash log is attached.
From first inspection, it's something to do with an event handler.
Thank you!
