Hey hey!
The initial bug of matching a Doomskull with Skulls in a 5 match, in a upside down T shape or L shape has been fixed in update 6.0.
I have tested the 5 match with Lycantropy Gem in an L shape, as well as the upside down T shape or L shape match with the Burning Gem and Wildcard Gem and no extra turn was given. I’ve reported this to the Dev Team so they can start working on a fix.
Thanks for brining this up
