It's probably waaay too late to be asking this, but how do we go about playing Steam Workshop maps? I know there's a tool for downloading them, but I still don't know how you'd launch and play them. I saw in Youtube videos there's a menu button on the Steam version for workshop maps, but not on the GOG one.

This is another sucky aspect of GOG, even when the developers are good about keeping their games updated here (which is the case with TO), we are practically excluded from basic things like custom maps.
