Oops! I actually am active, very funny to see my own mod posted on the thread I've been following for the past few days
As far as I know I need to restructure it so it uses something other than MTN, which seems to be outdated (as well as make all the changes to the map itself to fix the greenhouse issue). But for now I'll do my best to get it working as an IF2R alternative (since that's what I currently have permissions for) in the next few days.
Not sure if this addresses your other request but I do have plans to make a new large map with the same "mood" as that, but without being a modification of anyone else's. I'm still figuring out whatever 1.5 did to custom farm maps though. If anyone wants to reach me, I'm in the SDV discord.
