I was going to experiment more with the threads performance I noticed before and found "no threads to run the job" and encountered a crash when setting it to 1 thread.

It only occurs if you load the game with 2 or more threads, then set it to 1. If you load the game with 1, set it to anything higher, then back to 1, it does not crash with that error. Any change to greater than 1 must also be paired with a close and restart of the game.

Thanks for the report. It's now fixed for the next release. In the meantime you can work around the problem by disabling the menu simulations in graphics settings.
