Only the patched game crashes when I cross hubs. The original does not, and has the maze at map 41. The v1.0 I got from the CD, and the patch I downloaded from the raven games site. Using the patch, I also have the maze, and all my savegames are "erased" (I mean, they still are in hexndata but I can't load them). In addition, the cleric's health chain is deformed, it has a piece of the mage's chain.
I think that after installing the patch, I end up with a v1.1 hexen.exe but a v1.0 hexen.wad <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt=":?" title="Confused" /><!-- s:? --> And patch.exe says my hexen.wad is up to date.
