Why does the turret limit work like this?????

Why the fuck can someone put up a turret outside my tc range ina whole other base and it counts as one of my "12 max turrets" ??? How was this not thought through. so someone can just walk up put up a raid base beside my walls and put up 4 turrets ... and now all my outters will be disabled because they added turrets to the limit?? WHY does it not go off of whats in MY TC RANGE, or at LEAST turn make it so the NEWLY PLACED turrets are the ones that dont work not the ones that were already there. Actually so fucking irritating.

Edit: its pretty simple.. make the NEWLY placed turrets be the ones that dont work, not the old ones in the base. idk why its coded this way in the first place.
