I haven't deleted my tsw 3 version yet (PC). By chance visited TSW4 store page in steam and discovered one strange thing -if you want to buy a TSW 2 DLC for TSW4 you will see that price has grown up twice comparing the same dlc on the tsw 3 store page ( and you can still buy them). It is rather strange taking into account that TSW2 DLCs have not been changed fo ther new TSW 4 standards.
It’s a known store issue, it’s currently the weekend and as far as I’m aware DTG operates Mon-Fri, it’ll likely get Fixed on Mon/Tue it probably also takes time for the respective stores to respond to this as-well.
