Before posting, ive seen that a few others have encountered and posted the bug here on the forums.
The bug occurs when a player pauses the game, leaves, and game is resumed. The game however continues to collect resources, but you do not have any control except for the menu, the resource trade, and the player allies (navigation). You cannot scroll the map, ping the map, or control any hotkeys/units/buildings. I dont know if this would be easy to recreate, as i have had many other games where someone would pause then leave, yet resume normally.
I saved the replay, though it did not record the pausing/player leaving portion.
