I get the same error like Malagant (since Friday or Saturday, I think).
The crypt roofs are really cool and it's amazing how much of difference it makes to have them in the set. However, some of the pit roofs seem to not yet align 100% perfectly with each other and the bridge crosser still has those of the other crypt tiles.
Random bug report: The [Q] Sign 10 placeable is missing a texture.
Maybe too late now and I know the Q work schedule is quite full already, but as for some further content suggestions:
Placeables: Some more paintings and carpets/rugs would be pretty cool for more varied interior area design.
Creatures: Don't know if the LoW Yuan Ti Abominations Cerv was working on were finished, but those would be nice. Alternately, there was an awesome yuan ti model made by Baba Yaga which might fit even better with the general Q art direction.
Other than those, there are some more creatures (shadows and such, some of the demons, some of the birds, etc.) in the Arbor Falls haks which might be cool to have in Q. I also like the AD flesh golems.
Btw, I have to deal with some awful RL issues atm that prevented me from doing more tile stuff recently, but I still plan on trying to add those docks and some of the other stuff I talked about. Hope I can get back to it this weekend.
