Certain spells that grant single turn enchantments, when cast by The Amazing Reno, wear off immediately

I just played a game where I turned into The Amazing Reno. At the start of one of my turns, the hero power auto-cast Corrupting Mist with 3(?) minions on the board. At the start of my next turn, no minions actually died. The hero power then happened to cast Corrupting Mist again (likely a coincidence). Since I was now paying attention, I noticed that no minions actually had debuffs placed on them from Corrupting Mist.

Perhaps a bug with this being cast in the start of the turn, where the debuff is supposed to trigger?

The card clearly reads ‘can’t attack heroes this turn,’ however when cast on a minion by reno it doesn’t prevent it from attacking heroes as it should.

Seems like these effects are expiring before they begin. I was under the impression that the restriction on Charge was based on the NUM_TURNS_IN_PLAY of the enchantment due to #662 (which was retested). But that ticks up before the start of turn triggers. It should have been 0 in this case. So it seems some other start of turn effect, either not a trigger or in a later phase, removed the restriction? Would like to get a log of Reno casting this spell.
