@Roldy My reply wasn't directed at you, OP or this issue in particular, it was more a general observation.
The Known Issues list is shown before you have to enter any data about the bug and it takes a few seconds to login, searching the forum and scanning the Beta Release Notes can all be done in a couple of minutes so are hardly a preventative barrier to research an issue before reporting it.
Obviously there are more bugs than appear on the list otherwise it'd just be the bug database in list form, it's likely the ones that they've already had a mass of people report and so don't need or want any more tickets on because they have enough info and it takes time to wade through duplicates, but people don't check and report them anyway or are advised by people to report them even if known about because of the "more dupes = quicker fix" myth.
Not doing a quick forum search, glancing at the release notes and checking the Known Issues list before submitting a report just wastes peoples time, but then people also moan about how slow support is - well no sh*t it's slower than it could be - they've just spent the morning having to reply to 50 more people blindly reporting that <insert bug here> (which was fixed multiple betas ago + is listed in the release notes + is noted in the forum thread) and now it's early afternoon. It all adds up.
As I said it wasn't a direct reply to you, OP or this specific issue, just an observation at the lack of effort to research an issue before throwing in another report that will do neither party any good. It reminds me of people who write a paragraph on here/reddit/wherever and then wait hours for replies when typing a sentence into Google would get them an answer in seconds.
@gkri Did you try the original offending project in the latest beta and did it make any difference?
