This server is running a map you don't have

Hi there :slight_smile:
I am managing an Unturned server with a few friends, and we are trying to prepare it for launch. I recently edited the Russia+ map from the Steam Workshop for the server, and my friends can join it perfectly fine. We all have the same mods, but for some reason I keep getting this error: “This server is running a map you don’t have.” I’m very confused. I have deleted all of my mods, uninstalled Unturned, redownloaded the mods, still doesn’t work. I originally downloaded my map through the Steam Workshop and I got the error, so I deleted it and downloaded it through connecting to the server…to no avail it doesn’t work. Can someone help me out?
