Map got duped

Yesterday I hosted this map in a 6 men party:

When I first tried to open the map it took so long to open that I thought i forgot to click the open button.

After the map got open, it again took very long time to load that I thought my game was gonna crash. Once I entered the map i realize only 3 of us made it into the map. The other three crashed. We then went ahead and finished the map. Then the funny thing happened. We could't get out of the map!! I had to relog to get back to my hideout.

I did some trading afterwards and then just logged off. Today when I tried to play another map, I realized the map that crashed yesterday was still in the map device.

I didn't pick up anything in the map so I'm not sure if there was actually a roll back or the map just got duped.

Anyway I actually like this crash because it gave me a free map. But seriously it has been like 5 months now since 2.0 and the crashes are still happening. I don't remember having a single crash since I joined the game a year ago and before 2.0.

My previous reported crashes:
