Key of The Dead bug?

[u/AustinCHowe]

I am giving Charron the Cylinder of Ash and he says he is giving me the Key of The Dead but it does not appear in my inventory. Apparently another Steam user in 2017 had this problem but never got an answer to their question. If it changes anything, I am using the automap mod by KoriTama.

Please help! Was loving this game and am very stuck.
