Probably a good idea to upload the whole debug log:
https://filebin.net/988qrhjvvq0j05xj

Ok, the filebin files aren't avaliable, and I went to the Blood Lord workshop page to get more info about the bug...

...and you somehow managed to hit yourself while using the Handcuffs, while using more than 100 mods, and the creator of the Blood Lord updated the mod after the bug, and I'm not managing to reproduce it so far. Will try a bit more, but if I can't, I'm ending the work on this bug.

Ok, adding code to avoid this bug to show up again.
