Nyth and Sentrium Perfect Mining Bug

[Aquebus]

If you mine with a resource x 2 booster sentrium and nyth don't double to 4 and you just get 2 for a perfect mine.

Sentirum and Nyth's don't normally double without resource boosters.
How it usually works is that perfect mining has ~30% chance of yielding one of those two gems, rising up from around ~15% at base.
I believe you'd get 4 if you brought a Kavat and it's x2 booster went off while your personal resource x2 booster is in use.

This also is what I've seen to be true. The kavat is not always giving the doubling boost either during charm, that ability also gives other bonuses at times.

Yeah, 1 normally, no matter the Gem score, 2 with a double booster, 4 if your cat PROCs with double booster , and the very rare 8 if your cat Double PROCs with a booster (yes it can happen, I've only seen it once).

This has been known for a while sentrum and nyth only give 1 no matter the gem score. 

Since the gem type is not affected by score you can wave your mouse wildly and mine faster and you will still get 1 (2 with a booster)

Since the mining update, a Gem Score increases the chance at getting a Rare... so that is not a good idea in general...
