So I goofed and wrote a bad while loop to turn a tag on. I realized my mistake and tried to stop it and even deleted the script but it is still running somewhere. I have since renamed the tag and it does not seem to be a problem. How do I find where this tag is still being written from and how do I stop it. Thank you.

I hope this has convinced you to not use `while` loops in event scripts, unless the condition is certain to become false in a deterministic way. (That is, not based on an external condition, only on data already present in the script.)
