Following is an updated procedure for getting the crystal fragment. At least in Ferettmom's save both the world.x0 and objects.x0 file need to be swapped, since the crystal and sword both disappear when the mouse cursor is moved over them with just the world.x0 file. This may be due to a problem with that save, or a conflict between versions, since I started my game in an earlier version and installed patches as they were released.
At least in this case, the inventory may be the source of the problem. If I place the 6 *.inv files from my save standing at the well into Ferettmom's save, load that save and kill the mutant, it drops the crystal.
If you have both teleporter stones with you, you can do all of the file swapping at once, rather than having to swap files, clear the lower level then swap the original files back. I will describe this method below.
Procedure;
1 )
Download (1 MB) the zipped world and objects file from my save and extract them to a temporary location. This is the same link as above, I just updated the zip file.
2 ) After killing the mutant in the well, save your game under a new name, lets say 'well 1', for the sake of reference.
3 ) Create a subfolder in this saved game folder, and move your world.x0 and objects.x0 files into it. You must restore these files at the end of the procedure.
4 ) Move my world.x0 and objects.x0 files from the temporary location into the 'well 1' game folder.
5 ) Re-load the 'well 1' game, so that it is updated. The crystal fragment and unique cutlass dropped by the mutant in my game are now on the ground in yours.
6 ) Pick up the crystal fragment to trigger a cut scene, and optionally take the sword.
7 ) If you wish to rescue the other people, have one character stand as close as possible to the just revealed mine entrance, south of it and to the west, while the other stays back.
8 ) Save the game, named something like 'well 2'.
9 ) Copy the original world.x0 and objects.x0 files from the subfolder in the 'well 1' saved game into the 'well 2' saved game, overwriting the files there.
10 ) Re-load the 'well 2' game. The mine shaft and the area containing the prisoner will then be re-sealed.
11 ) If you are going to rescue the others, have the character standing in the central part of the well drop a teleporter stone, then switch to the other character and have them enter the mineshaft, which will be now obscured by a rock wall. After clearing the lower level and coming back up, you will have to click on the teleporter stone in your inventory to get past the wall, then (don't forget this) pick up the teleporter stone on the ground.
12 ) Exit the well, and explore the town if you wish, then leave town or try to re-enter the well to continue the game.
