I have 1 box that has the correct description ("With the puzzle solved,..."), and one box with the old description ("This ornate metal.."), 2 boxes in total.
It's v15 of the mod. I used the EE mod setup tool to install all my mods.
There have been some other minor strange things in my install, so it could just be my setup. But I thought I might as well report it in case the latest BG2 2.6.6.0 update broke something with the mod.
