Hello and thanks for the support.
The thing is somehow itch doesn't support downloading newly added assets to the bundle.You have access only to the assets which where available at the moment you purchased the bundle.Apparently I have to email them every now and then to "refresh" purchases, whatever that means.I did that but they reply so slow.
I was considering making a Patreon page in the next few days or anything that allows people to download assets and receive free updates.
As for now add me on Discord : wielen#6980 so I'll send you the pistol.
