Just finished a match in PvE with my Surprise along with a Snow against a Trincomalee, Snow and Brig. Within a minute of the cannon shot commencing the Brig sank. I didn't see how much damage it had taken but it can't have been a lot. Next I fired a few shots at the Trincomalee and even thought it had only taken minor damage it sank within minutes. The Snow behaved normally, finally succumbing to fire after losing all it port side armor. I placed an F11 bug report but has anyone else seen this strange behavior? I'm playing on the 4th Feb update.
