Runegraft of gemcraft bug

Runecraft of gemcraft gives my awakened added lightning and awakened ele pen gems +1 level on tooltip but does not actually affect awakened support gems- this is evident when going from level 4 to 5 and not giving my linked skill +1 to gem level.

Just got this and yeah, it's exactly what happens. Specifically for Raise Spectre and Awaken Minion Damage.

Just to clarify, you have the runegraft active, and if you un-socket the awakened gem, it is level 4. So does not have the +1 mod. Then you socket the gem and mouse over shows it to be level 5, with the plus one mod. However, the level of the skill gems it is connecting to is not increasing, as would normally be the case with awakened gems connecting to skill gems. Is this all correct?

Just out of interest, what is the skill gem you are using? For example are they ones that should be able to be supported. For example, for awakened added lightning, is it supporting a skill gem that hits?

If you've tested it thoroughly perhaps mention it on the bug section with all information. I'm interested to know because I might use it on my build too. I would test it but it's a bit expensive to use for testing when it is consumable. I think quite a bit of builds would be using this, so would think some others have probably encountered it as well if there is a bug.

Is it just the +1 level mod that is not applying? Can you tell if the other increases mods on the awakened gems are applying? I know it will be a bit hard to test since it applies all support gems. You would need to take all the other supports out and regret the allocated mastery to toggle it. Just don't scour it or you wont get it back. It's a small difference, but for example, in the case of awakened added lightning, it should be adding about 10 flat lightning damage from level 4 to 5.

I think this might be a bit of a new mechanic? Is there anything else that specifically increase level of all support gems globally? I can't think of anything. Maybe there is a mod or unique. There is a global mod for all skill gems and global quality. Also socketed support gems. No sure about this one though, it might be a new mechanic.
