Manalink 2016/01/15: Battle For Zendikar v2,duel

What exactly should be the correct behavior/interaction ?
Garruk, the Veil-Cursed abilities don't target if the 2nd ability has been activated before.

Are any other cards possibly affected by this bug ?

What ability was it using in your first picture? Because the only target among its abilities is what creature to sacrifice, and I've never seen that be 'random'.

The second picture is when AI uses 3nd ability -overrun-.
The first picture it is either 1st or 2nd definitely not 3nd I don't remember which though.I am the one who has Garruk, the Veil-Cursed and it was the first time I saw something like it.

OK, after much testing, when using the 1st ability the targeting graphic can be messed up. In addition to another copy of himself above his graphic I have also seen the graphic of random creatures in my hand.
