Severl Bugs with the client

[Zapherjin]

Hi guys, i just want to say that this is an awesome client! something i always wanted. Great job overall. there are a few errors which are sort of game breaking. A few times the game has just reddened out my main phase 1's and MP2's on about turn 2.

I am experiencing crashes when i play Oblivion ring, by tapping the needed mana before i play the card.

And the third, i get this
