What you were expecting to happen, and what actually happened
Since doomskulls are a special form of skulls, I expect an extra turn to be denied if 4+ are matched while the first troop is frozen. It doesn’t… sometimes. But not always.
How often does this happen? When did it begin happening?
After some testing, this seems to happen when a match consists of a mixture of skulls and doomskulls only if matched in a certain way. A match of 4 or more that is entirely doomskulls does not appear to ever respect frozen.
If matched in a certain way (presumably where the match is resolved starting from a doomskull linking to a mixture of doomskulls/normal skulls) this does not happen. However, if the match resolves in another way (presumably where the match is resolved starting from a normal skull linking to a mixture of doomskulls/normal skulls) your extra turn is successfully frozen. The second video shows both happening back to back. Note that the “corner” position of an “L” match in the first example where Frozen didn’t work was occupied by a doomskull, and in the second attempt where Frozen did work, the corner was a normal skull.
Also note that game speed has nothing to do with this. In the example I recorded, I simply turned it down so it would be easy to see that none of the matches that cascades or anything that was converted should have given an extra turn. I’ve powered through freeze with doomskulls and got the extra turn without cascading any non-frozen colors repeatedly regardless of speed.
Steps to make it happen again
Match 4+ doomskulls with your first troop frozen with both mixtures of skulls/doomskulls and just doomskulls and in different patterns to observe inconsistent behavior.
Doomskull explosions from matched seem to “beat out” simultaneous matches of colored gems, exploding and denying the 4+ match and extra turn… again sometimes. I believe this may also be related whether it is being counted as a “skull match with skulltype” or a “doomskull match with skulltype” and the order of resolution being altered accordingly. I have no recordings of this, but several people have reported it already in various places. Please consider also making these consistent.
