Okay, so at first I thought this was a weird coincidence, but it just keeps happening so? With the regular (non-experiment-only) zapper, whenever I get an experiment zap, my next color change is always the scribble version of that experiment. Every time, it doesn't matter what experiment I had. Then I get a random color change next time.

But I don't think I've gotten a color change other than scribble of the same experiment after an experiment zap, since the zapper was revamped :L

[edit] This seems fixed? I've gone from experiment to another pet twice now (I think both times were to a glade pet, but I'm willing to call that coincidence :P )

I have this problem as well.

I thought it was just a very common, weird coincidence as well, but it's just happening too often. And honestly, I'm getting experiment pets more than any other pet. It also seems like I can't get a swampie or a darkonite anymore through the pet zapper, without paying for the elixirs. S:

I've had an experiment pet change to something completely different without turning scribble. ...Though of course first it was the experiment, then scribble version, then regular version, and then something different so I'm not sure if that counts considering it did turn scribble.

I think that happened to me once too, in that pattern. But it was awhile ago and it's not like I've been tracking my zaps, just that I've noticed this happening a lot, even if it's maybe not 100% every single time :x
