I went to the construct screen for my new tech-adept. I think I modified the tracked Kataphron Destroyer and the motor idling sound was playing. It was still playing when I exited the construct screen. I was just standing on the bridge and it was still playing. Tried going to various screens and sound was still there. Tried doing a mission but was still there when I came out. Tried logging out and back but still there when my toon was standing on the bridge doing nothing. Really annoying sound btw... I tried restarting the computer but still there. The only way to stop it was to turn the effects sound volume to zero and put it back up when running missions. Something is buggy with the sound for the construction screen for tech-adepts.
