Stuck getting empty JSON responses on start_round

[Harest]

Not sure why yet. I kept receiving empty JSON responses while trying to start_round, x-eresult = 11.
Edit : Okay the error message with it is x-error_message | Already in zone game 2159. I've the feeling an error occured on the server-side here. Ideal treatment would be to detect this error number and leave the zone.

I feel like it's these lines. Gets set to undefined right before start_round is called, so the round isn't ended. No idea why it's only periodic though.

I edited my message. When i look at the log again, there's nothing abnormal. The score was submitted succesfully, so the game should have registered the fact i left the zone automatically. Instead i was stuck inside forever ^^. We just need to add a check if the header x-eresult = 11 and if yes to get the gameid in the error message (x-error_message) to trigger a leave_round on it.
