Hello everyone, I hope you're doing well.
Slipstream was updated to version 1.1.7, with a fix to the Xbox One controller vibration bug. I was able to reproduce the bug on both of my windows machines and the changes made to this version fixed it on both of them, so hopefully this will apply to all cases. You can re-enable controller vibration if you want.
Nothing else was changed on this version. I got some other bug reports (which I'll look into now), but this was the only problem that was reported by more than one user.
So... That's all. Thanks for playing Slipstream!
