Oh, I think I should note that the game is looking for scenarios in C:\Users\"myname"\AppData\Roaming\Blades of Exile\Scenarios, not in the actual scenario folder. If there are no scenarios in there, the game will tell you to put it in Blade of Exile Scenarios folder even though it's not looking there. It took me a while to figure this out because I didn't notice the editor was directing me there until the third time lol. The three starting scenarios work fine, though.
Also, I noticed the action buttons (spells, look, use, fight, etc.) are static, as nothing happens when I click on them. The shortcuts work fine, except for a (map), s (shoot missile), u (use), and e (end combat).
