Saved deck deleted and Solo Play not working

[Gutsy]

I made a deck, saved it, but woke up this morning for it not to exist. It was my only deck.

Also, whenever I try playing solo and have my deck selected and default, it says I need to select one (even though I have one selected). So I can't do solo.

Its a pain because I am brand new to the website and I can't even practice before facing others. Took quite a bit of time making my deck also for it to just evaporate into thin air.
