Let me amend it then, if you did not understand what I meant.
You left because you thought it was unfair for you to lose an ostwind due to a bombing run you could not see
Yes, I left the game because of that offmap.
The reason you left was due to that bombing run, you have said this... In that bombing run you lost two units, one was an ostwind, how am I wrong here?
Hence, the only logical reason for you to leave would be that you thought it was unfair/pissed that you lost units from what you say is a bug, and I'm pretty sure the replay will show the smoke so we've only got your word for that.
Even if you could not see the smoke were others could, it is not grounds enough to abandon a game, this is why I think you're a dick.
