file.Read not updating?

Hello, I am creating a motd for my server. I am using the script on 2 servers, the gmod single player server, and a actual server. To begin I created an HTML vgui and I am setting the html to be read from a file. Now when I test the motd in single player it works fine and updates when you reopen the menu, but when I add it to my test server it seems to not update. Even if I delete the test server file the HTML is supposed to be reading from it still displays the text I set before I moved it to the server. If I delete the file that the single player motd script is reading from the server script wont display text. Here is the look at the code:

local text = vgui.Create( "HTML", innerPanel )
text:SetHTML( file.Read( "data/motd_text.txt", true ) )
text:SetSize( innerPanel:GetWide() - 20, 315 )
text:SetPos( 10, 55 )

The code above is included in both single player server and actual server scripts as both the scripts are identical.
I tired to explain the problem the best I could, if you have any questions feel free to respond.
I’m not sure why it’s doing this. Any help would be appreciated.

Fixed (figured this out myself). You have to save the file the motd is reading from to the client by using file.Write.
