Slightly updated C# - but not quite sure this could solve your issue, since I can't get what's going on in your colony with this specific log only. As many other modders also emphasize, without full log, it's very little for us to do since we don't know what kind of mod you are using and under what kind of circumstance the issue is happening.

I'm sorry I can't provide more detailed information, to be precise, I don't know how this error occurred. But there was no such error log a few days ago.

I presume, in the process of many mods above modifying health scale of pawn, something that is not a vanilla case happens - I just added few safeguard to avoid null reference, but I'm not sure since at least five to six mods, including mine, modifying same data XD

I apologize for the long delay in responding. The truth is, I've been immersed in the mod experience you provided. Previously, I thought the game issue might have been caused by 'big&small', but I wasn't sure because I have a very extensive mod list. However, a new problem has arisen. When I use both 'MIM - WH40k Core' and 'Project RimFactory Revived' at the same time, I find that the slaughter machine is unable to produce meat. It's a very strange issue. I've included my error log below, hoping it might be helpful.

Then it should be highly possibly RimFactory is causing this issue. I haven't seen this "ButcheryFleshEfficiency" stat ever before, so I don't know how does it work. And your second log does not include any activity of my mod.

For the issue comes from a custom stat from other mod, I think you need to ask them to solve the issue, not to me.
