Change friendship here.
Can also cheat all friendships (of all villagers, for all saved players) to 255 by shift clicking the drop-down button instead.
isActive: indicates if the tile is animated (eg: bonfire has fire or is extinguished)
isSupported: layer2 tile checks beneath it (layer1) to see if there's something to hold it up on that layer (sanity check)
Dunno how to handle the isActive set-on-save. I saw there was an isActive flag in my plaza, assumedly left there from a radio or something. NHSE does not change flag state at this time.
