I've a new one! I experienced this a while ago, and just remembered it.
The Cloud 9 Counter Island(and possibly the Cloud 9 Counters too) from the I Heart The 50's set. I like to recolor one counter/island then copy it and place the rest I need. It's faster then dragging the color swatches to recolor. But this item when copied with the eye dropper, copies the original coloring of the item and not the recolors.
Did that makes sense? :?
Basically, when you copy a recolor of the island, the copy is the default colors.
