Ok, so staying up too late "one" night playing RDF/Mazz vs normal Mazz units I noticed an odd thing. At some point during the play (after 45 minutes or so) I noticed there were a lot of bright tealish colored dwarf bodies scattered around the map (kind of clustered). WTH? I didn't have any dorfs that color, and all the enemy dorfs are ghost colored. Turns out that something was seriously weird with the mortar dorfs - instead of shooting long distance cannonballs at me, they were lobbing brightly colored dead dwarf bodies. Also, and it may be intentional or a function of Mazz, but after the mortar dorfs died there was some kind of death from above - ala the pathfinder death when the pfinder has signal flares on him when he dies.
Of course this might have been the game that immediately went into OOS after saving it and trying to pick up where I left off - so it might just be my machine, or lack of sleep.
