I've been running both of your saves (Alba1 and Alba2) for a few years on our latest version. The game seems to be running fine without any issues. Since we have fixed many stability issues from beta patch 2.1.5.3 and 2.1.5.4, I suspect these crashes might have been fixed as well.
Hold on to your saves and try it again once we release a new patch.
