The quest says “Use a guard frigate’s Phase shield in combat to absorb damage coinciding with the shield’s tuning.”
I tried using my Zealot guard frigate to complete the quest and it doesn’t seem to be working. I tried removing removing all modules, removing it from the ship slot and re-equipping, and I can’t seem to get credit for doing the quest no matter what I try. I’ve logged out and back on, and done multiple PvE missions. I know my phase shield is absorbing damage because I get the temporary damage buff from it.
