Well if you're using 1.1 that's the answer. I'll bet johnhughthom has already upgraded to 1.2, as have I.

As I suspected, and the fact I use Steam means it's very difficult to have two EB builds...
I was able to have a go at a few battles though and was reminded why I first tried a Pahlav campaign, I bloody hate fighting HAs. Those catas just made it even worse, I really want to have another Pahlav campaign now...
