Zork Nemesis inactive hotspot

[upperi]

Hi, I'm using Zengine (Windows Current Builds 2012-03-20) to play Zork Nemesis on Windows 7. I've problem with crystals puzzle in Conservatory - clicking on rightmost crystal of the three next to the map doesn't work (it should play E sound). I've solved this puzzle by playing it with original Zork executable. There's save file from that location: https://dl.dropboxusercontent.com/u/96954238/nemsav1.zip I've also notice, that when playing with Zengine, the green statue keep giving me that tablet/stone/wafer - with original executable the statue gives it only once.
