Alright, I got saving more or less done, it seems to be working. It doesn't save everything a normal save file would, so I'll still have to add stuff later.
It says brick datablocks, color, positions, colorfx, shapefx, owner, etc. as well as all crop related data such as growth fertility and water level.
It also saves player's lots, seeds, and money.
It's set to autosave every 20 minutes, though it will eventually end up causing a lot of lag when it does try and save.
Once Momentum sends me some music for the server, I'll put it back up.
