If you leave the graveyard after exiting Iona's dungeon. Apollo (fat man) approaches you on the road. He normally turned up a bit SW of the graveyard. Please, try running around the southern exit a bit - it is a cut scene. And Apollo is looking for his friend Shrimpo. I'm sure, you can try again.

Or: check your conversation log, please => do you see a chat with Apollo? If so, simply click on the tombstones like this:
