Does Support still help you use the Rank Up Gem you want?
I remember seeing many threads about people saying if you want to use a Certain Rank Up Gem that is being covered by another one, you could contact Support and get them to activate the correct one or something... (Don't know why they can't just add that option in game since it's been an Issue for Years)
But I when I searched it here, a couple of the more recent threads mentioned they aren't doing it anymore or only doing it for certain gems?
I got a Generic 3-4 2017 Gem expiring I wanted to use on Thor, but a Cosmic 3-4 2015 Gem is covering it...
