Last night I encountered a pirate ship in tram, killed all the orcs except the red pirate, and did good damage to the pirate ship. Then my computer crashed. When I logged back in 5-6 min later, the pirate ship looked new again. But it was in a kind of limbo - staying at the same place but keeping turning around. I shot additional 15-20 heavy cannon balls/grapeballs but didn't see any obvious damage to the ship and I couldn't cast field on board. Short of ammunitions, I gave up and left. Anyone seen this before?
