Skaven Bubonic Court of Nurglitch
 

It reports erros of too many characters saying my units are more numerous than my mainstay unit. Bubonic Court list doesn't have a mainstay unit. Typical Skaven armies limit you to a cetain number of the same units based upon how many clanrat units you field. Meaning you have to field 2 units of clanrats if you want to be able to field 2 units of the same type of anything else.

A fix for this has been submitted to Robert.
