I have a very simple automation rule: when a linked issue is created, send email to reporter. Something weird happens, because it works only a couple of time and then just stops. There are no log entries in audit log, no error messages, nothing. Only thing which I have noticed is, that when publishing a change the rolling line stays circling over Rule succesfully published-icon. After that, when I recreate similar rule, it again works a couple of times and then stops. Any ideas?
