Hello all,
In the thread @Tabu shared, Gman updated that thread to let everyone know that we have been able to reproduce that issue and have reopened the investigation as to why players are experiencing this.
Although what Gman is referencing in that thread most recently, is related to Lycanthropy Gems and Burning Gems specifically interacting with Wildcard Gems.
In regards to what is occurring here, in the example given by @Dank this is correct, this is working as it should.
As there is the skull and an uberdoom skull now above and below the bottom two Wildcard gems, these are not resolving the lower Wildcard Gems as part of the horizontal yellow and brown gem matches.
Had one of those lower wildcard gems been a yellow or brown gem, then these would of resolved as apart of the initial match.
Had a play around replicating your board as well, both as it appears in your screenshot and tested if one of the lower Wildcards had been a matching coloured gem.
