So I just made a very large map (I combined every fight from the Temple of Scales adventure for one massive fight), and I went to test it out. On the very first enemy turn, Gary played a Run card for the 15 Lizardman Darters. It moved a few of them before the game just stopped. I was able to repeat this bug several times, and it occurred each time. The game didn't crash; I was still able to hover over my cards and see their targets; I could still hover over miniatures and see their lines of sight; I could also open up the menu, but resigning the battle didn't do anything. This makes the fight effectively unplayable. I've attached the F1 log, as well as the .scn and .brd files I was using if you'd like to test out the bug yourself. If I had to guess, I'm assuming this is because the game isn't designed to have 15 characters in one squad. Log: Spoiler
