We have sent 1.0.9 off to our friends at Steam, but they are really busy right now. As far as we are aware, the Mac version has been successfully delivered to the distribution servers, so those of you with the Mac problems we were experiencing should be able to get your fix.
As far as the Windows flavor of Dredmor 1.0.9: we sent them an extra copy just in case they left the first one in their pants pocket at home, so we are expecting it to be up sometime today. I will edit this post when we have confirmation of it being available for download/update for everyone. Thanks for your patience, we will get to the bottom of it.
UPDATE: Looks like Steam is slowly rolling out the 1.0.9 update. In order to get it to update quickly it is possible to delete the local files and reinstall, but those more patient than I should have it shortly (this will not erase the save files as they are stored elsewhere).
UPDATE 2: Some users are reporting issues with existing characters experiencing a teleportation bug. We’re working on it right now; if you do have this problem, just force-quit the game (ctrl-alt-del) and roll a new character while you wait; it seems to only affect existing characters. We will keep you up to date as we get more info.
