Hello, I’ve been making several servers these past weeks and for some strange reason everything I do on the server happens on my singleplayer server, this breaking some random addons I have when I just feel like doin some good ol’ sandbox.

Any way I could fix this from happening and remove ulx and all these other things?

Can you be more descriptive? If you don’t want something loading in single-player or vise-versa, add a check like this to the top of the addon’s loading file:

if ( game.SinglePlayer() ) then return end
