Cast on freeze + cold snap bug

Using cast on freeze and cold snap doesn’t seem to trigger cold snap. Cold snap is grayed out, but it stays at 0% when freezing

I have the same problem starting today.

I've noticed this today too, but before it already seemed buggy as there are many times I freeze, lose all energy and cold snap eats my mana, but the monster is still frozen. Since you can cast Cold Snap without freeze and it just eats your mana, I suspect that CoF+Cold Snap is just randomly targeting something else?

Also, on controller, Cold Snap needs a larger smart cast range. as frostbolts are consistently too far to Snap.
