Thanks for reporting the bug!

This should be enough info to implement a fix. The error dump was really great.

For now, the quality control mod is safe to disable and re-enable later, your machines won't lose progress on upgrades.

Ok, it should be fixed now. I'm at a coffee shop with my laptop and couldn't do extensive testing, so please let me know if you run into anymore issues.

Look working and stable, thx a lot. This mod is pretty much what I always wanted. Hope it's not too much easy to get legendary. So much option to control the balance is so nice. Thx a lot for this amazing work.

Thanks for the kind words!

Figuring out a good balance is pretty hard. If you think of it later, I'd be curious to hear what settings end up working for you.
