My friend and I were working on a Port Raid Mission on PVE server, had successfully boarded the Indiaman, but what seems to be a bug is that we could not access the inventory of the captured AI Indiaman, and were not able to get the mission chest. Leaving the instance showed that the mission was completed, but we received no chest as rewards either. I have a video from the end of the event that shows I was stopped nearby, and simply couldn't access its inventory. Before recording I had stopped at multiple distances and multiple angles, and sailed around it a few times too; I can upload this video if needed. Nothing worked, and we feel that we should not have been denied the raid chest due to a bug in the game...
