Sorry, I didn't find that edit in the log but I try to remeber it: Bot was running for several days in an infinite loop. I shortly logged me in as bot on de-wiki to change some settings. Most of my bot task stopped and asked for the password to continue on both branches (core and compat) except of one. It asked for a new token and continued, but it was logged out.
Version: compat-(1.0)
Severity: normal
