Summarize your bug I have been doing the Mythic Event "Pieces and Plans". The squad setup was zFinn (lead), Poe, R2-D2, Resistance Trooper and BB8 (Ally). When I used R2's Smoke Cover on himself my other characters didn't gain Stealth. They didn't have any effects that would prevent them from getting it. The ability of R2D2 is maxed. I am aware of the invisible taunt designed to spread opening damage and this is working wrong. I have recorded the fight for you and posted it here: https://youtu.be/aGTi_QfvMEY Please check.
Steps: How can we find the bug ourselves? Do the Mythic Event "Pieces and Plans" with the team mentioned above
