Seems that this is happening more often, where an event (like GunGame) will show that it's open (/events) though it's actually not. Only options are to Start or End the event, though nobody is in the event or even aware of it. Have to reload GunGame for it to start working again. 

I confirmed this happens when the minimum players is not met. If only 1 person joins, it locks up Event Manager and requires GunGame (or other modes) to be reloaded.
