TOPIC: Missing textures on the new map

Hi I recently came back to play zarp and i noticed the server map has changed so i went and downloaded the map
(All the content) And for some reason every time i join i see errors and missing textures everywhere (I have CSS content)
I asked a few people and they told me to install material content but i already have that so i reinstalled the content and it still doesnt work i searched for help on google but didnt find anything useful. Does anyone else has this problem?
Help would be thankful.

Go to their workshop, and download their error fixing addon. If it still doesent work download tf2. That fixed it for me

Can you send me a link to the fix addon
the only addon i found is Hospital door fix or something like that
I also have TF2 installed and it doesnt work
