[0.75 Tactical battle] Sometimes not clear in during tactical battles why you can't enter certain squares
First of all I'd like to say that I'm enjoying LH, it's a big improvement from FE but something that does annoy me from time to time is that during tacticle battles it's sometimes unclear why a unit can't enter a certain square.
Take for example this screenshot below. The square right above the selected Hero is inaccessible eventhough it looks excaclty the same as the squares around it.
