Problem with stacking Fur Squares

As the title suggests, I have a problem with stacking two fur squares, the problem is, it just doesn't happen. Anyone else have a similar problem? I've done a search on the forum and I cannot see any other thread about it, surely I can't be that unique.

Whenever I try and do it, they just swap positions and that's it.

If you look at the piles closely, you'll probably notice that they have different values. THis is something that happened in the last patch, when the availability of fur squares was increase, and the price adjusted accordingly. Unfortunately, this didn't seem to carry over to existing fur squares, so the game is interpreting them as being two distinct items.

Just sell/use your old Fur Squares. All the new ones won't have any problem with stacking.
