Attempting to switch out a reinforced/buffed creature with cause a soft lock situation. [Investig..]

I have tried unsuccessfully for days now to recreate this soft lock. But today hallelujah I got it to lock up. I know who get excited when you get a bug to work (this girl). Because when you get multiple players frustrated by a bug you can't figure out why it happened and can't recreate. It only frustrates them more. So please @Oktagon_Support this is a situation that should not be happening it needs to be investigated by y'all and fixed asap. Thank you.
