Hello sorry to hear you're having problems! I'm taking a look into this but so far in my testing with Autorun events I've encountered no issues. Any additional information about the event you're having problems with could help.

I don't know maybe I'm the only one who got this bug xD The solution is to change the event page from Autorun to Parallel, or to change it's self switch before it gets spawned. I'm just posting this in case someone else got this issue.
Srry didn't mean to sound frustrated. I've tried YEP's and GALV's plugins before that and it's by far the best one :)
