Updated the app, however, DLC locations went missing. I have finished the DLCs and have the underwears. Hopefully, it won't affect my game save in this 2.08 version. Please note that my inventory and underwears are currently present except for the two DLC location (Kronikos and HE!).

Hello, did you ask for a refund after buying the DLC? Are you playing an official version of it? Please, check if the DLC is in your itch.io library, that may explains why you haven't access to DLC content anymore.

No, I didn't ask for a refund and Yes, the game is official from here and the DLC is on my itch.
