Can't run a game on GUI.

[Ripper53]

Made a deck with 30 cards for Druid. Ran the deck, sometimes when I click the "Start Game" button, it crashes, or other times it crashes when I click the "'Player[2]' Move!" button. It's usually this error:
In "OptionNode.cs"

But sometimes other random errors occur.

When I run the deck with "Strategy" tab to "None," it gives this error instead:
In "GuiHelp.cs"

Hi, this is because right now not all wild cards are upgraded to the new system, so right now there are a few cards from The Grand Tournament, Goblins vs Gnomes and Curse of Naxxramas ... aren't useable ... Expensions 100% Kobolds and Catacombs (135 Cards) 100% Knights of the Frozen Throne (135 Cards) 100% Journey to Un'Goro (135 cards) 91% The Grand Tournament (132 Cards) (needs to be upgraded to new system) 100% Whispers of the Old Gods (134 Cards) 100% Mean Streets of Gadgetzan (132 Cards) 8% Goblins vs Gnomes (123 cards) (needs to be upgraded to new system) 6% Curse of Naxxramas (30 cards) (needs to be upgraded to new system)
