I found a few visual bugs you might want to take note of: First of all, when standing on a rising platform, like a platform floating on rising water, the character flashes, and also, when spectating while dead, everyone appears to be dead, and everyone appears to have the same time as you, as well as everything else.
Also, on the netcode side, The cheats and setlives commands are both personal, meaning someone can give themselves 99 lives and 9999 rings and whatnot. This happened in race. Also, when in DSZ2, the platforms that rise when you get there, around the end, they refused to rise for me, and then after going back twice, suuddenly they had risen, all on their own.
