Some Playermodels Not Having Ragdoll And Disappearing.

Hello, I seem to be having some issue with Playermodels on TTT. This is probably an easy fix, but whenever somebody is a certain Playermodel, Some do not turn into a Ragdoll upon death, and instead disappear. I have not been aware of this issue, yet, it may simply be an easy fix. I have searched before hand but could not find an answer. May I have some assistance?

Just an fyi don’t sign your posts. I fixed this issue by changing the ragdolls model to Phoenix or one like it, instead of to the players model.
