BUG - Victreebell Ability Grayed Out

On some turns, Victreebell's ability is not able to be triggered (the ability is grayed out and when I try to click it it says the requirements have not been met, even though it is a once per turn ability and has not yet been used this turn).

I use Victreebell a lot in games and there are several instances in which their ability gets locked up and cannot be used. I believe this happens when one Victreebell is defeated and another gets put into play. My assumption is there is some sort of setting which is locking the ability after or was used once in a turn that is not always getting reset (maybe even sometimes when a second Victreebell is put into play due to the code-behind not resetting the setting after the first one was destroyed).

Please fix this. My favorite deck to play is my Victreebell deck, but I have run into this A LOT and it is very frustrating to lose a game where Victreebell's ability could have let me win if it was working properly.
