We all know there has been some recent issues in the game over the past. I don't think it was fixed duel to its appearance to some people. Yesterday, POTCO was unexpecting network issues as stated on the website. The red banner of the network issues was recently gone, but the issues were currently not fixed. If I log out of the game, I am not able login into POTCO every 3 minutes, and then it lets me log back into the game.
Note: If you are having trouble trying to login, I have no way to help you other than calling POTCO to fix the issue. I really do hope these issues get fixed.
