Kitsame

Just kidding, another friend is having the same issue now. One friends able to join just fine, two cant join at all due to this prompt popping up. Both tried reinstalling completely and still no avail. 

Problem resolved on reinstallation of the game-- 

For anyone who has this problem and is looking for a solution, I was missing the playstyle content. 

Im running a modded server, and when anyone tries to join it prompts for mod downloads. They install the mods and then it prompts saying '0 Mods missing to join server'. Has anyone else experienced this, and if so were you able to resolve it? 

Any ideas on resolution are welcome.
