* Fixed the "Trun Telur 72hr bug" that starts just after reaching Trun Telur
and manifests by crashing the game after you teleport from Calisto's House
or if you rest for 72 hours after the battle at Trun Telur. I narrowed the
problem down to the NPC_ "EnderalFireball03", which if I removed from my
savegame using the Mash Removers feature, then my savegame after Calisto's
House would load fine instead of crashing. I presume the problem is that a
spell effect "EnderalSchuss01" may still be present when the fireball NPC
has been garbage collected, as I got a message about that spell when
loading a savegame where I'd deleted the offending NPC. Anyway, the fix was
to mark that NPC to be "corpses persist". Since these fireballers only play
a role in one "scene", I also unchecked the "Respawn" property. To be safe,
I modified all of the following NPCs in this manner: EnderalFireball01
...EnderalFireball05, and EnderalKatapult01 ... EnderalKatapult03, (8 NPC
definitions in all) since all of these NPCs throw the same spell.
