You are probably being disconnected from the Nexon server. I have similar problems, but for me I can't even trade troops in my alliance, and the game disconnects within one minute of loading. I have reported this to Nexon. Here is their response..."Thank you so much for letting us know about this. Our Development Team is already aware of this issue and they are working on a resolution, however we don't have a fix or workaround for this at this time.".... For me the game has been unplayable for three days.
