I took a look at the file, but couldn't find out what's wrong. Why don't you make the changes in vanilla names and descriptions optional? You can do so with XML Extensions.

Edit: I found what was the problem: some of the patches are for stats added by Royalty, which I guess should be listed as a dependency?

Also: loading the game with the mod https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2877266511 throws the error:
BotchJob_RockSmash (mod Possessed Weapons) sound is missing resolved grains and will not work properly.

Hey, thanks for the detailed report. I'll take a look later today and see if I can get it fixed.

You said you fixed it but Mod Error Checker is still giving an error: https://gist.github.com/HugsLibRecordKeeper/9cd6c5475bfe9e04b37cd61752567509
