Same problem, just spent hours alone spawning the stupid grophets for the datacrons, and went through getting all the buffs, just to arrive at the rock with the scanning skulls and find it un-clickable, and the blue beam wasn't lit, and the anchored rock wasn't opened. Killed everything in the vicinity, logged in and out, can't change instances because only 1 is available. This is very upsetting, and I don't want to waste my time getting all the buffs again.
