[.50] [Bug] Monster starting on invalid tac map square.
Started a combat against this brood warrior's army. The black widow at the top of the screen started on a square that you can see has no top grid border. It isn't a valid piece of terrain to move onto. I confirmed this after I killed it, it was not passable terrain for my units. While I was able to attack it, and target it with the impale skill of my spearmen, hovering the mouse over the spider told me it was out of range.
