Classic cards missing

Hello everyone,

This morning after starting hearthstone most of my cards have been missing in my collection. Yesterday the EU servers crashed maybe there is something link to that. Is anyone else experiencing the same thing?

I restarted hearthstone many times but it still occurs. After clicking "collection" it takes a long time to load.

I was logged off, my name was missing when I played a game. Some strange stuff was going on. But this morning all was fine again.
