Any workaround?

both
veh setDamage 0
and
veh setHitpointDamage ["hitEngine", 0]

should now work

vehicle engineon true; does not work, isEngineOn turns false after that.

Still broken after 1.80. Deserted vehicles respawn only once. Steps as reported before.

What I can tell is that there are still problems with this issue. The static AI substituting the player when disconnects are not longer present, but without SaMatra's fix there are problems when a player dismount a vehicle, disconnects or dies in the vehicle. I described what I found in a comment here: https://feedback.bistudio.com/T123940 Since the problems in disconnecting from vehicles (dismounting, dying in a vehicle) are fixed by SaMatra's addon it is possible that the issue described here is not completely repaired by the hotfix.

As far as I could see there are still problems with this module, when destroyed a vehicle respawns correctly, but when abandoned not. It will respawn only once if you use SaMatra's fix described in this topic https://forums.bistudio.com/forums/topic/202822-post-patch-update-player-disconnect/#comment-3164973 but the vehicle will not respawn at all if you don't use this fix, because the vehicle results still occupied when ppl dismount the vehicle, disconnect or dies (without Samatra's fix server side). So it seems this issue too https://feedback.bistudio.com/T123785 is not completely fixed by the hotfix. Tried in dedicated server.

We are having this bug in a MP mission, anyone knows the cause and possible solution?
