You're welcome & I agree with you, the lack of a stable save game function is a major pain in the *rse.
Bottom line: Ubi doesn't care. They have your $ and that's what matters to them. However I will say that they're not the only game publishers who release bug ridden products & then walk away from them.
If you don't have it already I'd suggest getting GWX (a freeware add-on) & SH3 Commander (also free). GWX fixes many of the worst issues in SH3 & adds new many campaign items (ie. the Indian Ocean, Black Sea). It's almost a complete re-write of the stock game. You can find GWX at
http://thegreywolves.com/ & look in the Mods Workshop section of this site for SH3 Commander.
