I took the following steps to fix the issue, but it still has me baffled.
- Rebooted.
Powered completely off and started back up.
Removed saves from save directory and started a new game.
Disabled all mods.
Removed all mods.
Verified game file integrity.
Deleted local game content and removed the x3 directory under SteamApps.
Deleted Egosoft folder in my documents and all temporary files from the machine.
I re-downloaded the entire game, started a new one and the issue still exists. I've never seen anything like it, is this a library issue or something? I've not installed anything else recently....
