Is there any way to force a clear of an event or function if it's been called too many times and is locking up the processing? One of my users has reported a bug where scripts don't appear to be firing and that's the only thing that I think could be a culprit. Other opinions on causes are very welcome, of course.

We'd need to have a look at the papyrus log to make any reasonable suggestions I'm afraid.

Ah. Thankfully, it was a null point! It was actually an issue caused by multithreaded events trying to work on the same variable at the same time and messing it up big time. I did a work around.
