Are you able to search for the missions in the user map screen? That's all I can suggest. I've just tried to sub to a random mission and it doesn't appear for me either. It only seems like this has happened since they patched the game

I don't get it; this is not an old mission that disappeared, this is a mission you just uploaded and I just subscribed to for the very first time.

Also, missions and maps don't show up in the mods menu at all, obviously, they're not modificatinons to the game, they're maps/missions to play with the game. They should be showing up in user maps/user missions, but they don't.

I found out this:
Once a mod has been updated on the Steam Workshop, players will need to follow a few steps to update and reactivate their mods: Disable the mod in the Mods Menu Unsubscribe from the mod in the in-game Workshop Mods menu Quit and restart the game Re-subscribe to the mod via the Workshop Mods menu Activate the mod and restart the game as prompted The updated mod should then work as intended

I know some of the mods for the games are down due to them updating the script for the games. I'll do some digging to see if I can find a work around for you buddy.

How the hell do you play these single player missions? I'm subscribed to them, but they don't seem to show up. You'd think they'd be in 'Mission select' and then the user created section, but that place is empty apart from a button 'user maps' and if you click on that you get a long list of multiplayer maps of seemingly every user map created; even though you're not subscribed to them. Scrolling through I can't really see any single player maps; and if they're somewhere there still; it's ridiculous that I have to scroll through a nearly endless list of multiplayer maps to finally get single player maps you're actually subscribed to.
