Well, consider yourselves lucky. I reached the last boss in this encounter (solo'ing it), Akris Veng and was standing on the platform sussing out the area. Np, bleed effect and interruptable heal, 50k hp's, throw another kipper in the pan I'll be home for breakfast. Then my group finder popped and I trundled off to do HM Hammer Station. Chose the 'return to previous' option at end of flashpoint.
So .. standing on the platform again with Akris Veng in my sights I notice a slight change. He now has 356,000 health points!! I throw caution to the wind and send Corso in .. who's dead in about 6 seconds with me not long after. Take 2 I call Gus in and kite Akris round the upper platform, Akris pounces on Gus (who's in 66/69 modded gear) and 2 shots him. I last a bit longer scampering round and get him down to around 80% before my luck runs out. Scampering around the upper platform with Risha pot shotting him didn't work any better.
I've tried resetting the local phases which at first it wouldn't let me do insisting I was still inside even though I returned to my ship, I had to travel all the way back to the fleet and go upstairs before it would let me reset! On heading back and jumping like a madman back to Akris .. 356,000 hp's!!.
No way am I abandoning in case I have to redo all the seeker droid stuff up to that point again. May try and bring a group in if I can get some guildies together who don't mind jumping through an instance to kill a pita boss for little return but for now open a ticket and hope for the best. :-(
