that's a new one. have you tried disabling all addons except for the ragdoll mover and see if that still will happen?

ok i'll try that

its working now thanks! i think i need to clean up the addons.

usually if you have time you can try the time consuming method to find out the conflicting thing - you can start with having only ragdoll mover enabled, and from gmod's addon menu enable addons, like 1 page of those, load into the map, check if error will happen, if no, go back to menu, disable that page of addons and enable next one, repeat until it errors.

when it errors, you start narrowing down the enabled addons from that page, like disable one line of those, load into the map and check again. and like that you should be able to find out what's the conflicing stuff, so if you have time you could check that, so i'd know what's causing the conflicts too.

I personally do not think this is a thing with the other addons. I remember before it stopped working, it was working just fine with all the addons, but then it decided not to work anymore the next day - I didn't add any addons at the time.
