Well, I found I might be wrong about the Es-Annon tattoo question. It does seem odd that the "better" way to accomplish the quest would give an inferior tattoo.
Another bug I found: if you become a Godsman before you deliver Giltspur's note, Keldor doesn't say anything and the conversation is immediately terminated. You do still get the XP from Giltspur though.
I purchased an engraving for Es-Annon from Death-of-Names but Fell is offering the Tattoo of Dreams of Es-Annon (which you're supposed to get if you tell the Crier to stop mourning) instead of the Tattoo of Graves of Es-Annon.
The fixpack says it makes Lowden a lot easier to talk to in the Weeping Stone Catacombs, but I can't see him at all anywhere, and I looked quite carefully in the crypt of dismemberment's underchamber ("hover over every individual pixel multiple times" carefully).
Any ideas what might be going wrong/how to fix these, or are other people facing these problems as well?
I have the widescreen, interface, fix, unfinished business, and tweak mods installed; I'd be happy to give more details.
