The message is harmless and happens when host chose a map you don't have as client. As for the video, I'm not sure what happened. Looks like a potential desynchro on gold, that's the only idea I have at the moment

"he will rot and after 60 seconds respawn"

I was able to reproduce a week ago, before we did a fix pass on the game, I couldn't reproduce since then So it should be fixed now = )

I had a look at the log, and all errors in there have been fixed for the next hot fix = ) So you shouldn't encounter that issue anymore after next update = ) Thanks for reporting ^^
