Anyone else having trouble with the syringer gun. Got the gun at Vault 81 but it never recognizes any ammo for it. Not the few syringes that I had found nor the few that I have made. Syringes don't show up in ammo, they are in aid. NEVER MIND, I FIGURED IT OUT. That wasn't exactly intuitive.

What was the problem?

Totally clueless now. Somehow I brought up a transfer window with syringes on the right one and a window for the Syringer on the left. Just hit the transfer arrow and the syringe showed up in the Syringer window. Now I can't replicate what I did so I'm lost.
