I'm experiencing this issue as well. I run RF on a Windows 7 Laptop, so I know this isn't a Windows 10 issue. Also, this didn't happen earlier this morning at 4am cst. Something changed within the last 10 hours to cause this, and it wasn't something on my end.
so im not the only one experiencing this, what I did was join a room before going into training and it worked for me, but getting kicked It d/c's me
This is happening to me too NOW.... Every time i join or make a room, it freezes then i disconnect from game.
