Playermodel Troubles, missing "vcollide data"

Greeting facepunch modelers, I am somewhat new to the process of converting & rigging models for Gmod.
I’ve come across this error in my console, and I have come across no solutions to this problem, much alone understand it.
Any and all assistance in tackling this problem is most appreciated.

The model itself is missing, hence why it has no vcollide data.

Whelp, time to dive back into files…
thanks and sorry if this does happen to be a simple problem.
