Hello,
mid 2023 I gave my old full steam - account "white" in the screenshots, to my son and we activated family share. All went fine until the guns dlc came around.
What I mean is, that we bought the other DLCs and all are visible on my new account "yellow" in the screenshots.
Sadly the guns dlc wont show up even as an option on my account.
We tried it on 3 Desktops and one Steamdeck and online there is no other one with this issue as far as i found.
It is totally okay for me to by the game and all dlcs again on the new accound, if neccessary. But I think its a bug.
Love all your fantastic work on Vampire Survivors. Got it on every platform we own. Android, iOS and Steam.
Best wishes
