I have had it happen to me once where I upgrade the laboratory while a research is going and it didn't pause it. Is this a bug or it's supposed to continue to research while upgrading?
Because here: http://clashofclans.wikia.com/wiki/Laboratory
It says "If you upgrade the Laboratory while it is researching, the research pauses until the upgrade completes."
Please let me know if anyone knows, I'm kind of curious.
