I think I found a bug with input. With my AI vehicle, he would continue to drive in a circle after being killed, which should be impossible since standard input is disabled. I checked the BP debug filter to check in realtime and I confirmed he wasn’t receiving any input. So I thought maybe mStandardInput wasn’t being disabled entirely, so I enabled it, set the throttle and steering to ‘none’, then disabled it again. Then the car wouldn’t move or steer, even though the debug filter said it was getting input and standard input is supposed to be disabled. My base player and AI vehicle are now the same, so I confirmed it with player input and it’s the same thing.
EDIT: I just confirmed it with someone else on a different machine.
