A wormhole damaged my ship beyond repair... does that mean I am now indestructible? :)

//edit: I used a savegame before entering it and this time it went normal.

Lol. Yeah, that happened sometimes, but not for a long time now. It usually happened when you changed ships in the garage and something made other ship's value messed up. Are you sure that the ship was at full hull when you entered wormhole? Maybe it was messed up when you left the station and you noticed it when you docked again?
