Currently I’m at ~40 bountiful delves done. However, I have yet to see a single curio upgrade drop (besides the Zekvir one). Meanwhile my friends with whom I have done several delves together are close to having all of their curio upgraded to 4/4 while they have done a lot less delves.
I understand they are not guaranteed drops and rng is in place, but with this amount of delves done and not having seen a single upgrade it does feel like this bugged for me/my account.
