I also noticed it not working. Lost my r2 immediately, no damage, no unresistable burn. On top of that the 15% chance to die worked perfectly. But I gained nothing from said bonus. Furthermore lost L3 next battle same deal, this time burn worked damage did not. The bossk was modded for health so the damage would and should have been huge, nothing. Nest ended up winning the whole thing because boba was already gone. Our strat also built around the idea you could droid suicide any han teams and that was a wash. As the first attempted team killed all droids with neither burn nor damage applying to anyone.
