I just had this happen in a raid. Magni was visible, so I thought just wait for him to revive, and level up mana - but he stayed in his ghost like form.
Turns out, it was Bold Tusk in the left wing that was invisible. What the fudge?
Several enemies with low hp have sharing damage. Sigle strike kills all of them. One of them was fighter (Boldtusk) and he reviewed. In this case game visualisated not a varrior but the most lelf linked hero. But its a ghost and you must hit empty space where fighter was to complete a battle.

It is just a visual bug, happened to me in the tournament also (did not recorded or made a screenshot, unfortunately).
Boldtusk revived as he should (he is fighter class), but alongside him also Sonya and Melandor. Very next move, I killed Bold only and won, Sonya and Mel were still in the ghost form.
I’ve experienced the same bug, but from a different side. My BT revived along with his Willbur friend. They had shared damage and wanted to die together, but eventually I lost the fight with Willbur still alive I have a video, but can’t post it here ¯_(ツ)_/¯
One of my fellow countrymen (a countrywoman, actually) has reported the same bug here as well, although it has not gained any attention, her posts not being in English. Anyway, she’s posted a video, too.
Poseidon (not Triton) can revive, after in ghost mode until the turn end, he will come back with 1 HP. The bug here is Frida who also got revived, just like the previous posts.
Fixed a bug where the wrong character appeared revived after characters were killed by Soul Connection damage and had the resist death talent activated.
