These are actually two occasional things that occur to me from time to time, usually on LIRR 1. This happened sometimes in M3, sometimes in M7, mouse in default look mode started moving on its own... usually helped uninstalling and reinstalling the LIRR DLC (+M3) 2. The other one happened like yesterday, Q as acknowledge key and mouse stopped responding, only turning the game off and back on helped... hasnt occured since - wonder if it was the game or stuff happening in the background Not sure why LIRR seems to be more prone to this, or if it is just purely accidental stuff because my PC wants to act like an a-hole
