Getting kicked out when starting a Map

Every so often when I load up a map in my hideout, when I go into my portal to start it I get sent back to the log in screen and when I load back in the map is closed and I have lost the map. Really sucks when the map is a good one and I dont even get to try it.

I've had this issue a week ago, two things I noticed:

- It happened more frequently if I alt-tabbed at the same time as I entered loading screen
- I changed the Gateway I was using from Canada to Washington and it fixed the problem for me

You can try changing gateway and see if it gets better. I know the pain, I would lose like half my maps and it was driving me nuts
