I just don't use the issue tracker. I don't believe any company who are serious about fixing bugs would allow reports of bugs to "expire", or allow previously fixed bugs to come back in updates. And if FD don't want to fix bugs, there's no way I can make them do it. All I can do is enjoy the bug-free parts of the game and work around problems (or, ultimately, find another game).
Expiring really old reports is fairly common and I don't see it as being a problem in itself - a lot of the really minor bugs will go away as a consequence of that bit of code having been rewritten anyway at some point in the last few years, and might well be something which happened to one person once through some unusual combination of circumstances. So throwing out reports which haven't had some minimum activity level after a year or two I could understand, and I know plenty of software organisations that clean out really old reports from time to time for that reason - though
they of course are using commercial or open source bug trackers whose purpose is to track bugs, so the submitter will get an emailed warning a month or so before expiry, and a simple "yes, still happening" response will restart the clock.
A one month expiry when there hasn't even been a client patch in that month, blanket-affecting all bugs which haven't been so serious to so many people that it's both overcome the obstacles to be reported at all
and obtained ten separate confirmations before that time? That's the ridiculous bit.
And agreed, there are only two types of bug:
1) Bugs so serious that the community managers will find out about them instantly anyway because of the forum complaint threads. These don't need reporting because Frontier already knows.
2) Bugs which won't survive the bug tracker process. These don't need reporting because Frontier doesn't want to know.
So far I've been lucky that none of the type 2 bugs have been ones which seriously break the game for me. I'm sure that luck will run out eventually.
