It looks like claiming a new territory costs a flat 140k and it gives you 3 days tax free. It would cost you 2x+ more in calibrate charges but could be used if ore prices crash and cannot maintain 1m a week.
I noticed Sinnen now has limestone instead of malachite- not sure if there are any other changes.
I think airbrake clearance zone should be a few tiles outside of the visble area of the element so we can continue to completely cover them but would still need to be near the outside and not stacked. The requirement of having them be on the outside ruins the look of many ships and makes all ships look the same.
I would like the idea of making a new territory unit item. Keep current Territory units the same- scaling claiming cost and no taxes- but lock mining to those tiles. The new territory unit would cost the flat fee and allow mining but needs taxes.
