Next year there will be a patch devoted to fixing up FR in terms of crashes and bugs using a different computer. I also plan on removing multiplayer as it is unstable and insecure and the mod would be better off without it. There are no plans for any new features.
I'm not even sure if anyone in the community even played the multiplayer as I didn't hear anything about it like bugs or crashes from the multiplayer. It always seems to be singleplayer stuff. I might keep it in if it isn't as insecure and broken as I thought.
Note that multiplayer would be just removed from the main menu and the mod will still support multiplayer through console commands. There would be a guide to set this up after the update launches.
EDIT: Multiplayer may not be removed in the next update.
