Augur of Cooperation; Solaire is Dead

[JakobKardeGaming]

I was in the Graveyard of Ash with Solaire, and a pus of man pushed him off the ledge. I tried to summon him back but he never appeared. I sat at a bonfire to reset, and nothing. I quit the game and came back, tried to summon him again. This time he appeared and died (I'm assuming from fall damage). Now, once again, he doesn't appear when I summon him. I fear I've done the unthinkable and killed the jolliest cooperator.

Update: Turns out dying resets Solaire, but not sitting at a bonfire, traveling or restarting the game.
