I also had the same falling through the floor right at the door of the terrentaket's room. There was no point to jump back up. Could fully walk under the vault room, engage the door to open, but nothing else. had to exit area to get out of it. The three imperial member squad in the middle, the 2nd boss, I can't say felt intuitive at all. Despite bringing opponents into the circles that were created by the grappler and the grenadier, no damage was being done. I could only brute force it as a DPS, and only got them to half health before dying my own self. Was playing as a level 75, 306 gear Jedi Shadow with a level 50 companion as a healer. Up until falling through the floor, I am enjoying it. The first boss fight had a nice mechanic that could be learned as you played with the falling rocks. I didn't figure out how to successfully avoid the stun attack, but it wasn't something that stopped me from completing the encounter. I appreciated that I could stealth past the Kath hounds and other trash mobs if I chose to at the beginning. I'm not sure what Yavork's pet thing was doing? I assume that will be part of an achievement. Destroying the consoles for the security grid took a bit of trial and error. The first time, I clicked, defeated, ran. and only when I pulled up the map again did I see that it hadn't changed. Ran back and this time remembered that the droid exploded, and was able to bring them down.
