Scarlet Witch’s passive (blue) no longer places purple tiles on TU tiles. 
Just noticed this as well. Used to not have a problem with tu tiles
I also noticed that 4* Cyclops blue can no longer target TUs as well. That changed just recently. Maybe even this afternoon.
I notice all the powers now say “basic” tile which is MPQ shorthand for tiles with a color only. Not sure if this is a silent update to some of these powers or a bug.
And I was wondering why I wasn’t getting much match5 from her purple…
Hotfix this please!!
And You get less purple than it should be. TU tiles no longer counted as basic tiles.

Working as intended, I’m afraid.
