I just finished the battle against Vezok and the game didn't crash. So, I downloaded the Save Files that was uploaded by Kralich/David, installed them and tested to see if it worked and indeed, it worked.

I had a saved game of Bionicle Heroes, which I tried to load with the mod (bad idea, the thing resulted in constant crashes, I could not enter any level) so I decided to start a new game, well, I completed the levels, no problem, but when I defeated Vezok the game crashes, and not only with Vezok, the same thing happened to me in the levels of Avak and Thok. Yeah men! I also had the same problem, I don't know if you were able to solve it but here is the "solution" I gave you.
