Isn't upgrading a railgun on mk5-8 to mk6 supposed to take 40,000 crystals approx. Its taking 100,000 crystals. Is it possible to add up all the cost it would take to upgrade individually (mk5-8 to mk5-9 and mk5-9 to mk6) and make that the upgrade price including the speed up grade charge?

Why is upgrading a firebird protection mk2-3 and mk2-1 taking same amount of crystals(15000)? The same exists for others too. Note this is the price to upgrade directly to mk3. After the update. Please fix this as soon as possible. Thanks
