1. Did you somehow shuffle those khan blanks to your deck? They are permanently added there if so...
2. This is a weird one, never seen or heard anything like that. Those icons should indeed have maybe a toggle or something. I have had some plans of actually allowing full scrolling of the map but haven't really worked on this game for quite a bit now. But will happen some time for sure.
3. Are you sure it wasn't because you placed a tile where the character could not travel to? Unsure if you're aware but that is also one condition for level ending. Hard to say exactly as the menu is in the way but these two tiles for example do not connect...
