Fixed it

You have to add a suffix to each version. Example: cbe_Wetmarket_v5 and write it in the exchange notes. The maps are manually uploaded to the servers. This means that if this new version is not uploaded, the players who have it will not be able to play because they will get a message indicating that they have a different map. The server does not download the old version as it sees that the player has a file with the same name. Administrators will not be sure if they have the updated version. You can try this on my server. You can change the map with the voting menu. It has the old version of your map. 45.235.98.26:27117

Oh ♥♥♥♥ you're right (I always wondered why there were a _vX at the end of most custom maps). I'll make sure to do that to every source engine map I work on from now on.

Also the workshop does not notify when downloading a new version. Suppose that I have the cbe_Wetmarket_4 version on my server and I see that on another server cbe_Wetmarket_v5, I will quickly know that there is a new version. And I will look in my files for the new version to upload it :).

Fixed the suffix issue

I have seen that the "materials/custom" folder with custom textures has been downloaded. Aren't they included in the BSP?

I did include it, but I saw that when I separate the materials file the textures disappear. I will look into it.

I lied, when I tested textures were in when I removed the material files from my regular game folder and custom folder

By "include" I mean that the custom materials are inside the BSP file. I leave you a video (min 11:36): https://youtu.be/lJ3oCs-52_U?t=696

This is done before the Buildcubemaps

I removed the unnecessary files

Good work!. It is already available on my server

halfway up the sewer there is a ladder to climb outside and place the bomb. Then you need to go back to the sewer and continue towards the end.
