In version 2.4.1 I found two copies of Nilfur's Boast boots. I extracted the bonus from one and wore the other.
Patch 2.4.2 modified those boots, and this immediately changed my cubed copy but not my physical copy.
If I wear my old boots and cube the bonus from the new versions, do the two stack or does only one version count? And if only one versions counts, which one is it?
