Building a turret on a ship during normal play (not shipyard). At a certain point the turret seemed stuck, even though there was no block causing this. Undocking the turret and redocking it, caused it to dock at a 45° angle.
Another player was in the top side of the turret while it was docked by me, who was in the base. The other player could move the turret normally for him, which would suggest it was a graphical issue. After he came outside of the turret and entered it again, the did see the same thing I did.
After undocking the turret again, and redocking it (collissions happened during undocking), it was normal & working again.
Edit: after relogging to get the server version, I saw this:
I undocked the turret, it came loose from the ship and started floating away. I rotated it and fired the docking beam, and got a crash (sent a crash report).
At this point I had to quit the game and restart.
Another edit, sorry. The server version is 0.199.466, I can't make out the numbers very well.
