Diablo 4 Season 4 Patch 1.4.1 Patch Notes
This is a tooltip specific issue with PlayStation that will be updated in the next client patch.
Players on PlayStation can still take advantage of the lower prices that are introduced in 1.4.1 for upgrades but they will need to initially have the investment listed on the tooltip which still represents the 1.4.0 prices. We apologize for the confusion with this and it will be corrected in the next client patch..
