We have a scenario that has shared player damage and so a player can be killed while inside a healthy vehicle if their team mates take too much damage.
When this happens Vehicle Snap errors.
I wasn't on the server at the time so don't have the exact error message.
Found when using version 1.16.3.

This should be reproducible by being in a vehicle and using an API command to inflict enough damage on your player to kill you.

Thanks for report, i'll check how to fix that. Using /c game.players[1].character.die() i got:

Error while running event VehicleSnap::on_tick (ID 0)
VehicleSnap/control.lua:102: attempt to index field 'vehicle' (a nil value)

It's not line 102 in 1.16.3 it seems.. I was still using 1.16.2 myself because it works fine in SP.

cool, glad it was reproducible :)

It's fixed now i hope. I didn't add a check for vehicle being not null because any extra code just adds to UPS. Instead using event on_player_died to recheck driving state. But if it continues to crash even rarely i might have to add the check.
