Resource not updating?

I have the evolve motd plugin installed but when I change the motd and restart the server it doesn’t change when I rejoin. Although once I delete it locally it redownloads it.

The plugin uses this code to add it

if (SERVER) then 
    if (file.Exists("evolvemotd.txt")) then

Also, sourcercs isn’t detecting it :. Have to manually sync it.
