Game freezes during deck creation/crafting


I have had the game freeze on me several times over the last week when I was in deck creation and/or crafting screens. Each time I had no other option than to shut the game down through task manager. As far as crash-type bugs go, it’s pretty benign. Not like it’s happening mid game, so the most I ever lose is a few minutes of unsaved deck building.
ummm… Lenovo Laptop with win 8.1 (64x), pentium, errr… something or another… too… lazy… for… details. (besides, for now I’m not even looking for a solution, I just wonder whether this is a known bug and other people are experiencing this. or if I’m stuck with it forever until the end of time. hmmm… maybe I do want it resolved after all)
