Without spoiling anything, are you accounting for stuff like a player saving in the Minotaur's Labyrinth without a... shall we say crucial item necessary for a trap scene?
In KQ6, the patched game prevents you from returning to the Labyrinth entrance unless you hold everything you need for inside. Stepping on the mountain will just not work. So you can save inside... you should be "safe" at that point (as safe as you can ever be in a Sierra game, lol).
