However, in the process something related to the render order got broken a bit, or rather, we found a bug in it and have failed to fix it - so far. The bug was that a stone underneath a building would suddenly appear on top of it if a unit was entering or exiting the building. Of course the stone shouldn't even have been there, but nevertheless, the sudden change of render order is a bug. It should be fixed sometime soon though, when it is I'll probably release a demo with lots of player colours..
Oh and, there is a max of 16 players, that should be enough but if it really isn't we could make it 32 or something like that (at the expense of some additional memory usage), does anyone have a problem with 16?
