Yes, the title says it all.

I'm not sure this is related to Godmode or Vanish (I have both installed, latest versions) or not; or any plug-in for that matter.  And I do not use Fauxadmin.

This seems to be related the no clipping abilities.  
One of my admins randomly goes flying across the map and then out to sea until death.
Seems to occur after they run cargo and then stand up from a minicopter or a rhib.

Any ideas?  I don't know how to stop it.
