Hangs at certain scenes at certain times

First of all, congrats for the new build! It's really amazing how the linux port is getting along!

OK, so sometimes I get hangs when entering play mode. What I learned so far:

1. It only hangs if it's the first time entering play mode.
2. It only hangs on certain scenes, and it looks like it has trouble when there's a "referenced behaviour missing" error.
3. The Editor never unhangs, and doesn't use any CPU during the hang.

That being said, I cannot reliably reproduce the hang, so any of the above points may be false.

I'm attaching a logfile of a session with a hang, hope you find it useful.

Keep up the great work!

Also, please allow .log files to be uploaded.
