Does it also happen if you test on a new map? Or just with your existing save?
The log just cuts off I'm afraid. Most likely it's too long for zerobin. We aren't able to provide support here on Steam, so I recommend you make a thread on the official support forums here:

You can attach the log as a file, so lenght won't matter. That's the best way for us to have a look at what's happening.
