We apologize to all who experienced problems with the game (HUD buttons not working). A fix for the issue is now live.
As a side note, we've added a small change to item crafting system:
Crafting skill now lowers the chance of getting poor quality items, catalyst rarity improves the chance for good quality items (smithy building is still required).
Note that poor quality have priority over good quality (it's rolled first and may block the roll for good quality).
