Once again I have to question the usefulness of the prime directive. They put it in all rulebooks saying they are not going to make official rulings for interacions, but then proceed to do it anyway when we ask them 
I'm not complining about the extra rule details of course, but if they're not going to stick to it, then why keep printing the formula into rulebooks?
Meepledrone can tell you. Default answer is. Sorry, we will not provide clarification due to mini was designed only for base game. So they are using this prime directive to not answer any rule question about interaction between any mini-mini and/or mini-large expansions.
Only think you can ask is interactions between large expansions except Exp 11. And partialy interaction between any combinations of mini 1-7 and large 1-2 because they were released in BigBox.
