need help if someone can.....just got into lv3, done the skeletons in the pit room, found the key to the next corridor, found the note and have stopped at the entrance to the Crystal of Life room because it's barred. there's an inscription about 'edge of life, shocking might blah,blah -- rest restored' near an alcove but WTF.....nothing i place there that has anything to do with fire, light or shock makes any difference the bars. i'm stuck playing the master quest mod -- maybe it's the mod or something i missed? pls advise....

PS....it's the mod -- reloaded an unmodded save ( un- Master Quested ) and got through easily but would still appreciate some advice on this situation from someone playing with Master Quest mod!
