Okay - I'll try to do some temporary fix for other resolutions for the next release (maybe later today). It might not look perfect, but at least it will be playable. Could you tell me what resolution you use?
I wonder why you couldnt move your heroes, then. Did you try a) ending your turn (this updates pathfinding) and b) sorry if this sounds silly but I guess I didn't explain you move using right mouse button click
