Telepath RPG: Servants of God buglist

[Strus]

Is it a bug?
Red lever in the crypt 3 right cellar.
"Attempt to move it": ~you hear a sound~
"Done" "~the sound ceases"
I've tried many times, with animation of the lever :
ended on the right,
ended on the left,
moved from left to right to left,
moved from right to left to right
and the circle light on the left cellar simply did not switch on"
I moved back to crypt 3 after finishing it, I guessed the door password , but i realised that I need to learn whole old alphabet to  open the riddle chests.
