Ok,
I uploaded four files:
1. a manual save I did (which might be right before/after the crash took place), it might not be sufficient to repro

2. an earlier autosave, if you use that as a basis, and follow the steps in the picture below, you should be good to go

3. a picture that shows what I was doing, e.g. fight beggar and get him to join me, then I went to either of the two spots indicated, got rewards, then opened inventory of sovereign, equipped ring of summoning *BAM* PC froze

The only crashes I had in Fallen Enchantress over 40+ hours, were just crash to windows desktop after extended playtime and multiple save/reload. Also graphics tiles would start to render incorrectly, allowing me to save, quit and restart the game to avoid crash to desktop. Whereas with this Legendary Hero PC freeze, it resulted in total system freeze which is why I wanted to raise the red flag.
One other thing, the beggar battle event is new to LH AFAIK. Maybe it somehow triggers a crash?
PS! You will notice I play with a modified map size, its slightly bigger than the "Huge" map available in LH, but I used the same map size for at least 20 hours over multiple games in Fallen Enchantress without any problems. And from what I read the LH code build should be better optimized as well?
