Got stuck in the M3S Covered truck.

I stopped the truck with some zombies chasing me.
Jumped out and killed them off.
Saw that two zombies stood in t-pose position inside the trucks cabin but still on the ground.
Killed them off without a problem.
Jumped back into the truck but didn't move it.
Jumped out and was then stuck.
My character is standing in the seat with the body sticking out of the roof.

Have tried walking slow, walking normal, sprinting, jumping standing still, jumping while sprinting. Crouch don't seem to be allowed.
Can't get back into the seat either.
Though I can activate the truckbed wich seems to be bugged (but that's another bugreport I guess).
Jumped in and out of the truck without a problem prior to this. Before I moved it.

I'm running my own local dedicated server.
Game version is: 1.10.153576

A "quick" update on the situation.
I figured I could change character and run all the way up just to move the truck. But playing with multiple characters seem to be a bit wonky in this game.
So instead of actually giving me the other character, it logged me back in as my main character for my LAN server. The truck was gone and I seem to have logged in were I were supposed to end up when getting out of the truck.

As a side note. The truck isn't even were I first found it wich was close by.

I'm having the exact same issue. In fact I've had it twice now.
I tried resetting the server and a few other methods but the only way to free myself was for another player to move the vehicle whilst I was logged out. I'm currently waiting for someone to do that again

I also have the same problem.

Can't commit suicide, can't open the doors or bend down.
The best idea I can come up with is to take of my shoes and run till I get a cut and hopefully bleed out. Ill let you know how it goes.
