I went to our guild hall in the Lost Precipice to check out the basic decoration costs to verify the patch notes were true. I went straight to the Master Scribe vendor and checked out the 3rd tab and all of the basic decorations still cost 50s + 2 crystalline ore at that vendor.
I then went to the basic decoration merchant in the market and he correctly sold the basic decorations for just 50s.
So at least the decoration costs has a work-around.
