Mods not loading in Titlepack servers.

[darkpuddle1]

I have a mod which makes the 2D grass decals in Valley invisible so you can see when driving on the grass - this mod is built in to my titlepack and saved with a track I made. When this track is loaded on to a server (not mine) within the titlepack, the mod does not load and you can see the grass.

Weird thing is in other tracks with the titlepack, the mod seems to work with theirs, so when playing online the tall grass is invisible - but not mine. I saved the track with the mod so it must be there, or does the server owner need the mod as well? Which is weird because they must have it if they downloaded the pack.

Not sure what's going on here.
