I found a solution, yet to mentioned it worked for me, when i got this issue, with 2 of my character, i tryed to abonded the mission of Forge alliance chain, and got back to fleet tolak to the droid, and continue Solo FP this worked for me, but this only work if you dont have completet up comming solo FP aka, finish Thyton, and shall to Korriban, and logged off, you need to talk to both again by resetting chain. that the bugg in the chain, seems that you need to finish up Prequels in one go, or the bugg hits you..
As i say, this worked for me..
