Bug with a 0/0 creature

Hesturk

So. Playing in Emrakul's Corruption. Vampire  node using Nicol Bolas. I used the 3rd ability of my planeswalker, reanimating Startled Awake which is now a zombie in addition to other type. I cast Kalitas traitor of Ghet and 2 Yanei. On the following turn Kalitas activate putting my Startled Awake at 0/0. But it stayed on the field, making the game unable to proceed to my opponent turn after I attacked.  Another event where I will get stolen of potential reward. This is beyond annoying and less than acceptable.
