Taking no damage

[Samson Whiteberry]

The other day a few guildies and I were leveling our weapons on the somewhat secret beach at Padres. I had tp'd to one of my mates, when I got there he said he couldn't see me but he could see the damage I was doing. He tried to tp to me and it said i was still in jail. Furthermore I wasn't taking ANY damage whatsoever. I rode with this glitch for about an hour and leveled some of my weapons quickly fighting undead Raiders and such. I decided to get greedy and try my hand at some stumps so I left for Tormentia, when I got there everything was restored to normal I was hoping to milk the glitch for a while longer.

Has this happened to any other pirates?
