lua/pac3/core/client/parts/event.lua:344: Tried to use a NULL entity!

your pac3 outfit failed to render!

seems to be same issue as #1326 , but, not sure.

Reproduce: sometimes appears on any map, but, easer of all - look at the skybox on gm_boreas(workshop map) using a pac_camera (camera outfit part).
same behavior even if pac_camera hidden, but, pac editor is opened.
