In the next patch evolving items that are lore will be going onto linked lore groups.
If you somehow acquired two versions of the same evolving item one of them will be removed after the patch.
I don't think this will affect most players, but this is a heads up just in case.

What does this mean? It means if you get an evolving item that is lore, you won't be able to have two of them in different states of evolving.
