The Blue Sun Mod

Without the crash info from the log file it's very difficult to pinpoint the reason for the CtD, but I'll try to help you with some speculations anyways.

It might be an item on the ground left by dead enemies, the smoke grenade is notorious for causing similar issues.

It might also be one of those weird issues you get when you play the game for too long in one session that has caused some of the quest files or characters to get mixed up.

As for solutions, try speeding up time and skip forward 2 or 3 weeks of game time, then try to enter the city again. If you enter the map without a CtD, the problem was caused by an item on the ground. If not, then it might be the memory leak issue and you might never be able to enter that town again, unless something changes in the quest or character code.

If you are familiar with editing the save game files, you could try to swap the map files in the corrupt save archive with one from a working one.

Well, that's what I can do to help with the information you have shared, hope you'll be able to continue playing, with Campecino fixed.
