Ah....ok... I... goofed up.. No surprise there. Part of the learning process.
I could have turned in for comms? But i wasn't finished? ..... turn in at Fleet? for a partial completion of the weekly?
Regarding my primary issue, So once i wait a week I can simply re-start again... yes?
Ops weeklies are up to last but one boss (which makes full clear DP runs hard to find) so according to your description your Weekly mission was complete and you could have turned it in. The final boss encounter is like icing on the cake.
The idea is providing a reward to groups who can't beat the last boss. At least you haven't wasted your time for nothing.
