Good morning. I currently have a crafted heavy phaser turret device in inventory - not assigned to a ship slot. I completed a Doff mission that provided me Heavy Phaser Schematic then started the Shipboard Engineering mission to craft a Heavy Phaser Turret. The mission finished after the alotted time, then disappeared from my Progression list. No Turret, Doffs disappeared into the void - not in sickbay and I lost not only the schematic but also the hard to come by Contraband commodity.
Can you only have one Heavy X Weapon Turret on your character? Did the mission fail and nothing was posted to say that was the case?
