Montresor_SP: When a bug is first opened, it gets the status "Open". Once Beamdog starts looking at a bug, it changes its status.
Yeah, right. If you refine the 'feature' to look for all bugs currently 'In Progress' there are none.
bugs that are, for example, "Submitted" - that means Beamdog is working on them.
No it doesn't. I have, like the other person, first-hand experience of submitting genuine bugs that get summarily dismissed or mysteriously disappear off their tracker. All that 'submitted' means is that it has been... submitted by somebody.
When was the last time Beamdog put out a patch?
(... But claiming they are not working on them, or that they delete bugs from the system, is just untrue.)
Then you know nothing.
