I'm not quite sure if this is intended or I've run into a problem.
But I just noticed that I can still stack -kunda and -kaja skills up to 4 times before getting limit reached.
And they seem to work as usual too, for example Matador did not use dekunda for a big amount of turns until he had 4 sukunda stacks on him.
Is this something that was changed in an update or some such? The description of the hack says it only allows 2 stacks but that doesn't seem to be the case.
