I just encountered a problem...
I just started playing, and I got past the 4 trials, (I noticed that Spirit also has a dialog bug, which if you don't fight him (the last option), Freedon registers it as you beating him.) after I defeated the Freedon Spirts, I ran right through the exit. I did get to go back to Tsig, but for some reason the supposed dialog that is supposed to trigger there doesn't happen. When I reloaded my save game, I couldn't go through, or even open the door at the end. I could only go through the door again if I reloaded a save before I went into the tomb.
There is probably an easy solution to my problem that I'm just not seeing...
