You could alternatively use dev commands and just spawn in the item you were supposed to get. It takes like a minute.

you need to enable console in steam valheim properties

then press F5 in game

type "devcommands"

then type "debugmode"

Then type:

spawn (item name) (quantity xx) (Item level xx)

Should look like this

Spawn torn spirit 03 00

Although, if this was messed up there is a good chance other stuff is too. A new world might be better.
