I was just messing around a bit when it suddenly crashed and i couldn’t start it again. Always crashes at 71%.

Do you have the error message available?

Usually in my experience, I crash for one of two reasons:

  1. I fail to initialize a variable before setting things in the constructor

  2. I try to access an object that I am not allowed to access.

Furthermore, a solution will only fail to load if the setup itself is bad. If it tries to call a method in-game it will crash then. Unfortunately your code is a bit choppy above and I don’t see anything off the top, but I am willing to bet you forgot to initialize an object, then tried to access it.
