I'm unsure if this is a bug or not.
It was in Conquest, but I don't think it would be just Conquest specific.
SEE (with Booming Voice) vs an OG Boba-Bounty Hunter team.
The Bounty Hunter team reached contract and thus received the Boba revive.
There were 2 Bounty Hunters left Cad (I think) and Dengar, who was under stealth.
SEE linked Cad and the team assisted because of Booming Voice. The team killed Cad but he revived due to the Boba contract. SEE then linked Cad again (the only choice as Dengar was under stealth) as the second part of his link.
The end result was that only Cad was linked and there was no opportunity to link Dengar.
