Two blokes at my club were playing WFB a little while back, Orks vs Demons, and a strange situation occurred. Now Ive been playing a long, long time and I have to say Ive never come across it and it stumped me.

Some Demon Screamers went in for a slashing attack on some Goblins, triggering the Ball and chain fanatics.

Now the rules for the Screamers say they skim over and make attacks but cant be attacked back, but the Ball and chain fanatics rule says they are triggered, move out and dish out their unpleasantness to anything they encounter.

Thoughts?
