**Ok, here is my story:
I casually went to update gmod and I got to like 90% of the update and then ran out of space on my main SSD, so I moved the steam directory to my 1TB hard drive then re-updated gmod. Before the new update I had NO errors. Now I have many errors, TDM Car textures are fucked, and worst of all, gmod is unplayable because I get random freezes every 5 seconds in multiplayer servers.

If anyone can help me with this issue please reply below. Thanks.

  1. Validate your Garry’s Mod files.
  2. Follow these steps
  3. TDM being fucked up is the addons fault, wait 'til it updates.

Thank you. This actually helped

Please mark as solved if you need no other help.
