The upgrade screen closes after upgrading. Is this by design? This might be a matter of personal preference, but I feel the screen should stay open until the Done button is used. Also, using the Done button sometimes triggers the twinkley upgrade sound.

Rain of Arrows has a strange delay. When casting this ability, there's a 5-6 second delay/stall and then damage is inflicted without animation. It worked fine the first time, but not since. I was using an Ignys Shortbow.

Invisible treasure tile on the strategic map. I randomly found a treasure tile which I could click on, and loot, but which had no graphic to represent it as a treasure tile.
