Im not sure, but I saw a ZombieHorde in the minicopter passenger seat attacking the pilot, I wonder if that could be the reason?

It was actually sitting?

Changed Status from Pending to Closed

Changed Fixed In to Next Version

yeah I saw it with my own eyes

JUST FOR YOU.. now you've seen it  the zombie is attacking the player

They should be blocked from doing that in 0.5.8, which should prevent the error as well, hopefully.

while players enjoyed them joining the copter. thank you for attending to that
