I know alot of people have had the issue with random crashes on turns, which end up making that particular game unplayable.

I had the same issue, and found a fix that worked for me if your on Steam.

Simply have Steam re-check your files. If your not sure how to do this:

Go to your Steam library -> Right click Fallen Enchantress: Legendary Heroes -> Go to Properties -> Local Files -> Verify Integrity of game cache

Let it do its thing. When its done scanning, it should say 1 or more files were missing, and automatically download them. This -should- fix your CTD problem, It did for me
