--- Comment #7 from Kunal Mehta (Legoktm) legoktm.wikipedia@gmail.com --- It looks like this bot is running in autonomous mode with -force option enabled. You should not use this option but -cleanup instead. This behavior is a crossnamespace conflict starting on the article namespace on one of the remaining sites. I guess a not registered (this means neighter mw nor pwb) namespace alias is the point. fi-wiki is on the cross-namespace exception list for article namespace and still remaining. This is indeed a well known bug. But the best solution is not to use -force for namespaces or disambiguation conflicts.
