Hi Salty,
I don’t know if this issue is fixed in 0.36, but it is still occuring in 0.35.1.
Sadly, I realized that the screengrab here is not the greatest for highlighting this issue.
In the screengrab, the yellow gem on the far right of the second to last row is “match-locked” from a previous turn’s skyfall into a yellow match. That match was then broken by big gems generated from matching Shaman potion gems which overwrote the supposedly locked yellow match. I’ve also seen the gems generated from the Shaman potion gems overwrite each other when being generated.
