That was my bad, as I helped port over the Dynamic Trait system and added an extra line somewhere that broke the mercenary system. The issue is caught and fixed, but the fix hasn't been committed yet. You could either wait for that, or if you're comfortable editing Python (you can do so in Notepad): open Mods\Ashes of Erebus\Assets\python\Screens\CvMainInterface.py Search for: inputClass.getFunctionName() == "TraitButton") Two lines below that you'll see a "return 0". Delete that line. This should be save game compatible. Also, something I've noticed is that when I make manual changes to files, it doesn't update those files when I do a full SVN update. So when the SVN update goes live, you'll need to right click the file, go to TortoiseSVN, then revert and press OK. Then you right click again and hit SVN Update. That should give you back the little green checkmark.
