We have the option to abort the mission, maybe it would be good to have something like a 'complete the mission' option as soon as the objective is complete (or with a 1min delay), which would teleport you to the exit and finish the mission (maybe with a confirmation just like the 'abort' option). For short missions like Capture/Rescue this could be disabled, only endless missions and open world (caves) would really benefit from it, it could also be an option to bypass the extraction timer.
It could help with problems such as getting stuck (and /unstuck failed), bugged, or current Zariman exiting problems (such as, if you wait for the rest of the team enemies can shoot you, you cant shoot back, exit timer is at 0 but no extraction, extraction console doesn't work aso) and it could help to not lose (in the worst case) hours of progress.
