So, I bought a Mamba and am engineering it, and decided to engineer the pulse lasers. I didn't have a recipe pinned, but didn't feel like flying out to Broo in my Mamba, so I flew there in my DBS and pinned a recipe, then flew home. Then I changed my mind and flew out there again and pinned a different recipe then returned home and switched to my Mamba, but in the pulse lasers didn't appear in the remote engineering interface. So, I thought I needed a grd 1 upgrade, so I flew the Mamba out to wierd and applied a grd 1 upgrade, but after returning home again, it still didn't show up. So, do I need to actually fly the Mamba to Broo and pin the recipe? I swear I was able to engineer other things with existing pins, so what's going on? Is it a glitch? Is there a limit to active pins? Do I have to fly the Mamba to Broo and pin the recipe? I don't want to fly out there if it isn't working.
