Can't leave spawn

I was playing Camille today in blind pick and the game took alittle longer to load nothing special, but then I finally loaded and tried to walk out the spawn and there's an invisible wall blocking my way out. I was able to move, but I couldn't move out of spawn I even tried flashing my way out no success. I reconnected only to find myself stuck in a slow load and come back to the "Leaver buster disconnect" window, which booted me out forcing me to reload AGAIN! I reloaded FOR THE SECOND TIME and I was able to move out the spawn. Only after the gameis over I end up in "leaver queue" please help.
