Additional things:
First, it's somewhat annoying when you add random new fields that have to be literally searched through the entire world in order to randomly see a line with (0).
Second, or kinda additional to the first one, the same goes for finding random new Digimon (that are field conditions, that is) who live nobodyknowswhere.
Third, "sudden attack"... what the quack is THAT supposed to mean? It explains exactly NOTHING about how I can actually achieve or trigger it. This one is VERY annoying, because I don't even know where to start looking for it.
