You can reach anything you can see. You can build anywhere you can see.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.

My reach was pretty short after the update (~32 tiles), but I just changed the distances in the mod settings then changed them back, and it seems to work now. (edit: until I changed another mod; then I had to do it again)
I just loaded the map with Long Reach dissabled and saved. Then i enabled the mod agian and it worked.
