Gem cost bug when upgrading

So today I was upgrading my Hope Bringer's Chestpiece to Champion:

Wow I didn't know you had to take off any chips embedded. So ok, lets do just that

Now here comes the nasty and unpleasant surprise:

I was like WTH is this serious!??

I tried removing a level 5 Obsidian I had on a Sword. It cost 200 gems!!

I've seen other concepts like this (Might and Magic, etc), and none cost anything to remove embedded chips from equipment.


Tynon, is this intended? or a bug?

If this is intended, no one would ever bother with level 4 and higher chips at all. The effects are not worth it.
