Enemy B2 gaining TM when my chars are damaged

Metasly

I noticed a strange bug :
- My Tie Fighter Pilot blocks enemy B2 abilities
- Enemy B2 gains a turn and attack
- Enemy Wedge uses his aoe ability, none of my toons have any counter-attack
- Enemy B2 gains another turn and use his special

It was during an arena fight and I noticed the same happening another day

That's how he works. Chance to gain 100% TM when one of his allies is damaged or one of your characters evades one of his ally's attacks.

Hiya!
This does not appear to be a bug! B2 can gain 100% TM through his unique "Relentless Barrage" and Ability Block does not prevent unique abilities.
