Recently someone hacking away at DOS extender code stumbled on the same bug and fixed it independently. https://www.vogons.org/viewtopic.php?p=1007153#p1007153 https://www.vogons.org/viewtopic.php?p=1007153#p1007153 "New version 1.7 of DOS32AWE released, the download link is in the first message.

Could be useful in other games too."
