Hello, thank you so much for reading this

I every now and then when I load map I will spawn on the very edge of the map of the pit darkness anyways how do I stop this respawning in this area

also how do I get my rag-doll back in it's normal form with out deleting it I have one trying to pose and it's arm is broken or something and I cant seem to fix it

Thank you guys so much.
