I was at the portal in 1-1, get up to get a drink and when I get back, I can't move.
I click and click and then I get the message "Your ship has no more hitpoints...etc" and get kicked out of the gamescreen. I get pissed, but as I am about to buy a new ship, I notice the repair-button isn't there.
I log out and back in again...and the game loads, my ship is fine.
Must have been a bug. Sure, it is not a big one, but I wonder if this has happened to others and if they have wasted credits on this. Sure scared me.
