Caused game to crash in development mode, not sure how to search.

I do not know how to explain this problem. Tried to implement loops for redundant tasks and game crashed in development run. Attached files with specifics of crash. May affect future versions of game and modding, then maybe not. I would like to receive some constructive feedback and do not really know who to ask, as there are multiple bugs in the attached crash report. I included the part of my code that is buggy for reference, the rest is unknown to me.

Thanks!
