The previous Official Game Feedback had no more room, and hadn't been updated for almost two years. So here's a new one!

This thread is for posting bugs, issues in the game, or any other minor improvements you would like to report. Do not post suggestions for new elements or features here, those should go in the feedback forum.

You might also consider reporting bugs on github, so that they don't get lost.

For more complete changelogs, see the snapshot changelogs or the Github commit history

@levonchic (View Post)
Middle mouse still seems to work for me. And i'm also on Ubuntu, using the 64 bit linux version. Does anyone else get this problem?

@MrDucku (View Post)
I haven't seen that either, maybe try deleting powder.pref. If that is the issue then maybe send me a copy of powder.pref (with the login info removed preferably), so that I can try to debug the problem.

Or maybe try redowloading it. There was an issue with 91.4 the first time and I undid the update until I could push a fixed 91.4.

): it would really be nice to know how people are getting these broken powder.prefs sometime though
