In Selene's Web, adds on the final boss fight can occasionally become stuck and untargetable.
When the adds first spawn, they spawn as invincible, untargetable NPCs (the in-game nameplate is green). Once they jump into the battlefield, they turn into hostile NPCs that can be attacked. However, it is possible for them to not convert into a targetable NPC, as shown in this screenshot.
In this case, the Mender at the top got stuck on the web and never fully completed the jump-down. However, they were still able to launch attacks (though with all the other incoming damage, I could not tell if his attacks actually did damage or not--but there were definitely projectiles being fired by this green-nameplated NPC).
Reproduction of this issue is inconsistent. I did a handful of Selene runs yesterday for the pledge, and this happened only once.
