Save corruption

Very sad. I am getting save corruption now in the campaign and much earlier than turn 60-70s. I am not even to turn 20 and I cannot load any of my last five saves. Playing as Dwarfs. Every time I try to load a previous save, I get a ctd. So, this new patch is actually worse than the old one.

I am using Gigantus' install with his modified 1.5.1 patch. Anyone getting corrupt saves?

edit: I started a new campaign and now am at turn 40s. I appears that something bad happened in that last campaign. Looking good so far with this new campaign.
