I'm having the same issue as well.

Go to the mod settings and open the body parts tab. Select the modded body type and click on auto assign. Manually assign anything that wasn't assigned automatically. Thats it, youve created a compatibility patch

so had this happen too, the way to fix is to unbind everything, go to a different body type then back to human and auto it again

Also some effects, for example Choking on Blood, which is very important to see, just isn't listed when using the fancy tab. This should appear as it affects the whole body, but it doesn't appear anywhere if not seen through the vanilla tabs. Could anything be done with this?

That's a totally separate issue, unrelated to More Injuries. I actually came here to make a post about it myself.

Its not possible to select more than one body part for one body part

(example: more injuries adds femoral and popliteal artery, but you cant choose both for the same leg)
