Description

I've filed a very unnecessary bug which I wasted hours (mine and yours) on debugging it (sorry :disappointed:), while the problem in fact was a corrupt poetry cache. Please work this simple suggestion into the bug report template so we all wouldn't need to tread that swamp again.

Thank you :heart:
