I've ran into an error for the second time in the past two days and it appears to be a type of error that, destroys the integrity of game IF you save it following this exception.
As will be obvious to the developers, this error occurs when I am exploring a den (in this case a lion's den). The error actually permits you to continue, but crashes (Civ4 must close message) if you continue to the end of your turn. As I indicated above, in the event you save AFTER the above error and try to reload from it, Civ 4 crashes (again) with a "must close message".
Here's the verbiage; hopefully it will help:
Traceback (most recent call last)
File "CVSpellInterface", line 32, in cast
File "string", line 0, in ?
File "CVSpellInterface", line 4383, in spellExploreDen
File "CustomFunctions", line 755, in exploreDenBigBad
File "CustomFunctions", line 102, in addUnitFixed (I'm not sure if I have the name right)
Runtime error from Unidentifable C++ exception
Last night I hosed my game by destroying the integrity of my save (I hadn't saved for a few turns and was playing a "hotseat" game -- by myself -- and was so frustrated I didn't continue.
Anyway, just to let you know, I think that you guys did a masterful job designing this game. Thanks for the fine effort!!!
