My suggestion is that in /k upgrades, you can upgrade max claims infinitely. But it must be getting more and more expensive that at some point it becomes extremely expensive. I already have everything maxed in /k upgrades and can’t do much more with mana
I checked and you’ve not upgraded/levelled everything
Max claims does not need an infinite amount of levels atm, only 1 or two kingdoms have it on max level, but dont have max claims.
