I put a descent amount of testing into this, and what I found is that if the "enable ragmod" config is left unchecked then a few problems will arise. The biggest is that all of my attempts to spawn props and entities from the spawn menu or toolgun played the sound, but otherwise did absolutely nothing. Even pushing z afterwards does nothing.

Also, another issue I found is that when I killbind (I am not sure if this applies to all deaths) my camera will follow any trajectory I was on, but no rag doll appears at all.

I appreciate that this mod has the option to disable it conveniently placed in the options menu, in case I ever need a break from it. However, my guess is that disabling in the options menu does not fully stop its effects, leading to some weird bugs. Best wishes!
