"Supported co-op with modded trucks:
When a client joins to host with mods, all host mods are automatically downloaded"
With the speed issues we have with mod.io, if clients are downloading from mod.io and host has 15/20 mods installed, it could be an hour before they're able to play. Whereas if i just uploaded from my own connection it'd be a min or two. But do we know which method they're using?
