There's a bug on Divide, Dorfball, and Keep (Assassin gametype). Sometimes you get "standard" brown units. I've seen other weird mixups, like the unit taking on the other team's color or turning a weird shade of green.
The similarity between these 3 maps is that there are different units that share the same sprites (Herons and HGHs on Divide, Bowmen with and without flames on Keep Ass, the 4 dorf types on Dorfball).
Well, most of you probably already know this bug, but I just noticed the similarities between the maps I've seen it on and decided to make a post about it, since it does affect gameplay on Divide and Keep (but I think it makes Dorfball even more fun). I was curious if anyone knew anything else about it. Maybe it could be fixed in the next update?
