ToME: the Tales of Maj'Eyal

The Vaporous Emporium shops produced today...

Pile of Gold
Herbs
"Poster"

The top two not so big a deal, a minor loss.

The last one meant that the lore was not generated, nor was the shop icon created on the world map level.

Fortunately, the last one you can drop and pick up to get the lore, but that is not really obvious.

The poster was set to be transmoged/aped.

If I remember correctly, this is known, and you get the lore if it were to be transmogged. That said I'm not entirely sure, so you might wanna wait from confirmation from a dev. Also you can take it out of the APE and 'use' it from your inventory to read it as well.

I honestly don't understand the your issue. You say "loss" and "not generated". It's very annoying that all items from the loot chests and shops - including recipes, gems and lore - go into the transmog slot, but you can just take them out as any item from there. No need to drop it.
And as the previous post said, you can also read the lore like any other lore item.
