What were you expecting to happen, and what actually happened
Smite, Defensive Aura, Protection From Evil not working as described. Too often (today) green gems are created.
How often does this happen? When did it begin happening?
Seemingly fairly consistent today. Green gems being created in place of yellow. Some yellow gems are created but far fewer than normally expected. In the case of Protection From Evil, purple gems are destroyed but rather than gems dropping to fill in the gaps, there are a bunch of other gems being converted to green.
Steps to make it happen again
Used as normal. Nothing special.
