CTD During Battle

I'm playing a Saba campaign in version 2.3 and I have been repeatedly experiencing a CTD during battles. I have attached the log file and I would appreciate any help with solving this issue.

While there's a lot of content in there, I can't see anything obvious besides regular trace.

The last bits of processing have a big gap between them and the crash itself:

It seems that the issue has been fixed, but I don't have the slightest idea how that could be. When I played again earlier, I experienced the same crash as before, about halfway through the battle. The very next time I restarted the mod again after that, the only thing I did differently was to disband two mercenary units that I had recruited only a few turns before. Since doing that, there haven't been any more crashes during the battles. I've even recruited those same mercenary units again to see if the problem could be replicated, but still no crashes.

Thank you for looking through the log file. It seems everything is good now, even though I don't understand how.
