Never used Warcry, but it looks like there are compatibility problems. Let's see if someone else can confirm this, and I'll add the info on the mod's page.
I took koki's suggestion and moved the OBSE_SS esp immediately after the WarCry esps and Voila! - no more missing mesh problems. I really like this mod and I'm glad that koki was able to resolve this issue. Thanks to everyone who took the time to look into this matter.
