As stated in the title, under certain circumstances the game treats one key-press as two: pressing 'D' will cause the tech to make two small jerks to the right, opening the bug report or rename tech menus and pressing 'A' will print 'aa'. Interestingly, pressing 'Shift+A' prints 'aA'. Also, no matter how fast you press 'A', 'Shift', it will not affect the second letter, printing 'aa'. This also happens on 0.8.0.1 unstable. Pressing 'B' while out and about will cause the build beam to appear as normal, but after a short interval (from about 0.2s to 10s, it appears to depend on lag somewhat) it will disappear again as if you pressed 'B' again. Likewise, pressing 'Esc' will open the menu and then close it after a bit. By 'certain circumstances' I mean pretty much all the time for me, but I will have certain periods where I can play for a long time without it happening, and then it's as if it toggles into the buggy state when I quit and re-log. When I first came back to the game after 0.8.0 (I last played shortly before 0.7.6 I think), I did not have this problem, but I think it first appeared when I re-logged after crashing from clicking on a Twitch stream link in-game, and it didn't go away after a bit of re-logging after that, until it eventually did and I was able to play for several hours without this bug. Then when I re-logged (I'm not 100% sure if I was able to re-log before the bug reappeared), it came back, and just now I reinstalled the game and even that did not get rid of it. I should finally point out that I'm not having this bug in Firefox as I write this nor in Reassembly so I'm pretty sure this is a TerraTech problem rather than a hardware one (which on the face of it it seems more like). Sorry for this rambling mess of a bug report but I haven't the faintest idea what's causing this (a variable thing that persists through reinstall seems pretty weird) so I just put down all the info I could possibly think of. I tried to look for a log file but there is no such file in my 'TerraTechLinux64_Data' folder.
