New invincibility glitch???

[bpg2012]

Okay, i was boarding public ships today and when i tried to board one it said, " could not successfully board ship because the crew boarded a flag ship " so i figured i would wait and kill something well when i attacked it it hit me but it never took any health away, i was on my new pirate so i attacked the highest level i could find and it was still not hurting me it lasted until i logged off the game.

p.s it worked even when i went to a different island unlike the kings head invincibility glitch
