I found a Pancor Jackhammer Blueprint for sale in Beth's Gun shop in Hub.
I was suspicious- why would somebody sell that? Is it a rare saleable item spawn?
I bought it anyway, thinking it would at least be a rare collectible.
When I got back to my tent I decided what the hell- read it (I have Small Guns Prof lv 2).
Blueprint disappeared, and I checked workbench to see if the Pancor Jackhammer was on the list.
It was not. I was disappointed but not surprised.
Here are screenshots:
Is this really a bug, or playful trolling from the Dev Team?
