Bug: Cards reducing cost not working

I am running an ogre heavy deck, and currently the cards that reduce cost for other cards are randomly not working. I’ve had this happen with the Krog, the ogre kIng, with the Ogre Dance, and the Ogre negotiator. It may be happening with other cards as well, but it effectively makes my deck useless.

Does this happen always, or just occasionally?

There are cards that can’t be reduced (weird rules, not 100% sure if they’ll be changed).
Did you have Radiance or Primal Colossus in your hand?

There is a graphical effect that shows which card is being reduced. Did you see this effect on a card without reduction? Which card(s) received the effect?

On a related note, in one game I played I saw Goki didn’t receive Magda’s cost reduction.
