I haven't found this question anywhere on here, although I'm fairly sure someone has come across this problem before me. I made a mod that I wish to play with my friends and my Organization but I can't load it on multiplayer. Does it have to be loaded server-side too? If so, how can I fix this?

You have to submit the mod here and wait for it to be approved by an admin.

Also i think that all your friends must have this mod etc.

I have my mod (I attached it to this post) but for some reason it will not upload. It tells me that it needs some sort of prefix. Does anyone know how to add this prefix? The mod works fine for me in singleplayer, too, so I don't think there is any MAJOR error with the format.

ALSO, how long does it take for them to approve a mod?

You know, I didn't get an answer yet. I either bump this or make a new post, I really need to have this problem solved.

The mod you uploaded didn't have that so it would have been rejected.

Or it just hasn't been approved yet.
