Unexpected disconect

Hello, I was running a normal 76 Precinct map and i went in my hideout to sell stuff, i hanged around for like 6 min and when to go back in the map i get disconnect immediate after loading screen(I couldn't see the map). Oh well isn't the first time when this happens, I lost a portal not a big deal. But the problem is that after i logged back in and i used the next portal, the same problem occurred, lost two portals. And then again, my 3th portal is gone with this "unexpected" disconnect. Now I'm sitting in my hideout with my last portal, wondering if i should go or not. Am I the only one having this problem?

Edit: Oh well, my last portal died too, what should i do now? I don't want to risk the same problem with my next maps.
Edit2: After running other maps I didn't encounter this problem again. Seems to be a short bug.
