[Lord Plothos]

This is the infamous looting bug. It's due to a conflict between the game and directx 9.0c, which was included in windows service pack 2. The problem has a couple of easy fixes, though. My preferred method is to do this:

Download and apply Atari's patch 2, then download and apply Moebius' temple.zip fix.

The other method is to simply download and install Atari patches 2 and 3.

You can get the atari patches from here:
http://www.atarisupport.com

Get temple.zip here:
http://www.jadri.com/temple.zip

To install this, install patch 2 first, then copy the file "temple.dll" from the .zip to the game's main directory (thus replacing the one there), and then transfer everything from the .zip's "data" folder to the game's "data" folder (thus adding to it). And that's it! Fixes the looting problem and much more, while remaining compatible with all the fan mods (which is why it's better than atari patch 3).
