I have done it before, but with this mod, it doesn't want to work. I am trying to download Beg_Ballgore.tdm. But I can not get it to work. It works in Single player, but just resets the current mod in Multiplayer.

Any Help would be appreciated.

First of all, tdm.?
Try uninstalling beg_ballgore.tbm and using /mod beg_ballgore.tbm (I can't remember if it was /mod or something else. Somebody will have to confirm that for me) to re-download it. It should fix your problem.

My bad. Meant to type tbm.

Anyways, I have no idea how to uninstall it. I've gone into the file folder and deleted the file, but it still pops up in my folder on Toribash.

Are you getting the mod from a thread? Or are you using the mod search function?

I got it from a thread.

Did you use /lm? If so, try loading it from the menu. Upper-case and lower-case matter when doing /lm.

I believe mods have to be approved before you can use them in multiplayer. Not all have been approved yet. This is probably why it works in sp but not mp.

This isn't the case anymore, mods get auto-approved upon upload to mod system.

As it was mentioned, mod names are case sensitive. You don't need to have a mod if you play on multiplayer - it will automatically download for you. Make a room and type EXACTLY /set mod beg_ballgore.tbm then /reset.
