During the game, on turn one, the game completely skipped my upkeep, so I was unable to cast Vampiric Tutor during my turn to put the spell I needed on top of my library.

Then, on the following turn, I used Vampiric Tutor to search for Necromancy and put it on top of my library. I drew it and cast it, but for some completely inexplicable reason, the game decided to cast Necromancy AS AN INSTANT.

Because of this, the creature I reanimated immediately died, completely ruining the play and potentially the entire game.

Seriously, what is going on? These are not minor visual bugs — these are gameplay issues that directly change the outcome of a match.

Please go back and REVIEW THE GAME LOG/REPLAY. You will be able to see exactly what happened. I want an explanation for why my upkeep was skipped and, especially, why Necromancy was handled as an instant in a way that caused my reanimated creature to immediately die.

For an event where players are spending real money to participate, issues like this are simply unacceptable.
