Potential Issues for the coming expansions

I figured I would create a place to list potential issues between existing characters and future expansions.  For now, I only have one:

Setback + Mr. Fixer - What happens when Mr. Fixer has Jack Handle and Setback has Friendly Fire?  Does Friendly Fire trigger Jack Handle again or is it a corner case where it just deals Setback 2 damage?  If Friendly Fire does trigger again, can it trigger again off of its own triggered attack?

The short answer is that it does not make an infinite loop, mostly because we said so.

This has been discussed before, several times, but I don't remember what the official result is.  But it's already been resolved, and just needs to be implemented when Setback is added.
