okay, so replaying through Imperial Felucia to grab some holocrons, i discovered a nice game-crasher bug when you try to enter the elevator into the Sarlaac. After a little experimentation, the cause seems to be costumes. At the very least, basic training gear (your starting costume) seems to crash the game at that point. This is on Xbox 360. I've gone past just fine with the jungle gear you normally wear for the level, and i might try out this crash with other costumes later.
So, irksome to say the least, but not particularly horrible. Just thought i'd put that info out.
I'm replaying that mission now, once I get to that point in the level I will make sure to make another post as to whether or not I experienced the same problem.
I played this level again with the Sith Robes on and had no problem using the elevator to get inside the Sarlaac. However, once I was inside I slid through the side of a wall and got stuck but all I had to do was exit and then go back to the save point and was able to finish the level without a hassle.
Assuming you're getting the flurry's timing right thru all 4-hits your copy might be a bit bugged. Mine worked fine though on 360. Man some of those training modules are crazy hard!
Yeah, I highly doubt he's still having this problem seven years later, buddy.
