Warning - Don't merge units after battle before saving.

[Slaists]

I just fought 3 huge battles with the Mughal empire as Marathas after i surrounded their capital city which had 3 full stack armies stood around it, and when it came back around to my turn, before saving i tried to merge the units in the only army of mine that got beat up considerably and the game crashed to desktop. I tried to load the auto-save but it had only saved before i fought the 3 huge battles, so that was 2 and a half hours wasted.

I auto-calced them, but the outcome was that i won all 3 battles still but took way more casualties than before and didn't capture the region.

This (and other ETW CTD crashes) are system specific. I've done pretty much the same as you and no crashes... Actually, I have had not a single ETW CTD since I started playing. Sea battles, land battles: all stable.
