I can't grab seats

In my server i can’t grab seats.
They are like holo’s.
How can i fix it?
Also i removed some content from orangebox/garrysmod/models
Can it cause it?

What you should do is ask other people to move it.
If they can it is a problem with your GMod. If they can’t then you need to run
HldsUpdateTool.exe then type in Command Prompt (CMD)

cd ((Where you saved it))

hldsupdatetool -command update -game garrysmod -dir ((Where you saved it))

No brackets.
If this dosen’t work then delete all over your “hl2” and “orange box” folders then do as said before.

i just ran steam update!

Did it work?
