So I decided to test out some jets in gmod. I was on the map flat grass and I spawned a F-4 Phantom II jet. Everything went down hill after that. When I got into the cockpit of the F-4 Phantom II jet, the map completely disappeared. The only thing that I could see was the sky template and the bugged jet. I started getting an insane amount of lua errors caused by WAC Aircraft. I clicked disconnect and spawned the map again. The map was still invisible. I went to other maps and it was the same result. No buildings, grass, floor, etc. Only a blue sky.

This is the lua error:

[WAC Aircraft] lua/entities/wac_hc_base/cl_init.lua:544: attempt to call method 'GetLastShot' (a nil value)
1. DrawWeaponSelection - lua/entities/wac_hc_base/cl_init.lua:544
2. Draw - lua/entities/wac_pl_base/cl_init.lua:105
3. unknown - gamemodes/base/entities/entities/base_anim.lua:49

If anyone knows what this means and how to fix this, please don't hesitate to tell me. I've been trying to fix this since yesterday but I can't find a way to fix this problem. This never happened to me before the recent update. I would appreciate any sort of help.
