Problem with upkeep cost mod

[Darkness1990 6]

I've found a big problem with the mod, If I set the free tiles to 121, it gives players 121 free tiles every time they resize the deed.

 

For example they make a deed 5x5x5x5 or 11x11 (121 tiles) then they resize to 7x7x7x7 or 15x15 (225 tiles) because the tile difference is only 104 tiles its applying the 121 for free every time.

so they just keep expanding under 121 tiles to exploit the system and get tiles for free.
