Stuck in the fountain

Had a game recently where our Diana loaded in like everyone else but it had showed as if they had disconnected but was still able to type and move within a confined range in the fountain (the circular area). I tried replicating this with some friends but couldn't seem to figure it out. Just throwing this out there incase someone happens to run into the same thing with themselves or one of their team mates. Diana was able to continue the game and leave the fountain after having to close their client and reload entirely.
