It's very quick and easy to save in this game if you do it via the keyboard, so I save before every crystal when I'm in there, because some of the rear ones in the double sets are actually useful.The really bad bug was linked to 4 squares just north of the Tomb of Terror. If you entered any of those, the game would crash and hang the computer. The only way out was to unplug the computer. However, each time you went through this procedure, it would leave a sizeable "lost cluster" on the hard drive, and I know one guy who blundered into the area so often that he filled his hard drive with these and rendered his computer unusable. (Bear in mind that in those days, an average hard drive was about 50K!) I suspect the guy he called in had to take the disk out and slave it to another computer to tidy it up!
