I hoarded all my GET2 and the Acklay mission put me over the top to 7* my Malevolence. I saved in case Malevolence was added when others were buying Negotiator or gear.
Imagine my excitement putting months into this, after having this TB delayed due to problems with the other TB, to finally use the Separatist capital ship in the Separatist game mode.
One problem: you won't let me use it, for some mysterious reason probably that amounts to "oops" on your part. I can only select Tarkin or Thrawn, even with a fully maxed Negotiator.
This is incredibly frustrating. My feedback is get your act together.
