When the QAR came out, some old servers were added back into the game as well. I've had three very strange happenings when I went on today, and I was only online for five minutes.
When I logged in, Navona and another ocean were blocked off. They said quiet but the text saying the name of the ocean was red. I switched to something else, then clicked on Pirates again, and both of the servers were gone. I went into Sabada, had another experience (below), then I was about to switch servers again when I saw that Navona was back, but not the other one. Later on, it disappeared again. Disney probably noticed the problem described on
this thread and were trying to fix it.
The second strange experience was when I came online for the first time. I got the Queen Anne's Revenge message, but a few seconds later I got several messages all saying about the treasure fleet. I opened the map and saw that there were lots of lines all around the map. The game obviously duplicated the treasure fleet.
The third and final problem happened when I switched servers to do the Queen Anne's Revenge, then went to Sabada again. It showed me a picture and a message, like normal. But the load bar never showed up, crashing the game. When I got back online, I saw the same thing happening with Sabada as the other servers. Then it disappeared.
Pirates is pretty bugged up now. I hope they fix it soon.
