Doom skulls are not considered for hints

Platform, device version and operating system: steam

Screenshot or image:

What you were expecting to happen, and what actually happened:
The hints (highlight of the matches) ignore doomskulls matches, if there are no normal skulls included. It will highlight 4 dooms + 1 normal skull match, but will not for 2 + 1 doomskulls.
AI unaffected, it picks them just fine, it only matter for hints.

How often does this happen? When did it begin happening?
All the time

Steps to make it happen again
Pick some skull-generating team, get Slayer Ghost to turn all skulls to Doomskulls, check the highlights of matches available.
