I was in a 3-player lobby, and on the final map of a mission, connection to the host briefly halted. Me and the other guy reconnected almost immediately, but could no longer interact with anything including doors and items when prompted, and could not harm enemies. Enemy tracking was also delayed and struggled to hit us at all.
Jumping back to hanger after this resulted in me getting booted back to main menu, all mission progress was saved correctly, but both the other guy's and my own inventory were rolled back to before the desync.
Loading back into the lobby without restarting the game didn't cause any issues, but when we loaded into the next mission, I did not have the option to interact with ANYTHING except for the jump map, which I could interact with at any distance and through walls as long as it would have been within my field of view.
I also couldn't fire any weapons or pause the game to restart, alt+f4 was my only option.
(video shows the final part of this bug, will later post the entire relevant part of the session when desync started)
