I am setting a timer on an event. When this timer has expired and should trigger its delegate event, the game crashes. This even happens if I reset the timer before it should trigger, somehow keeping track of the original time when it should trigger. This is very odd and kind of hard to explain… see below
Hard to debug without seeing more of your BP. Start adding breakpoints and seeing where it crashes. Does it crash the editor, or just the game? Is there an infit eloop in the delegate? Need more info.
Yeah it seems I had an infinite loop elsewhere in my script. I was blaming the timer as that was the last ting I put in, but it actually HAD NOTHING TO DO WITH IT.
Move along, nothing to see here 
Glad you figured it out! A break or a set of fresh eyes can do wonders!
