1.30 BUG Exploitable Build Plots

[MrMikey]

Found an exploitable bug with plot management... make a plot in a cheap spot (ie far away from high ways) and pay for it... then move it close to the highway where the price is what... 10x? And just add 1 and remove 1 from the same axis... and you can confirm the new place for 0 additional credits IE it wont update the price difference from spot 1 to the new but rather seem to take the price from the old cheap spot even when enlarging it.
