Has anyone else experienced problems with your Piscis plants when they've been harvested.  I have already grown and harvested six.  I know this because (1) I grew them and harvested them and wrote each colour I harvested on my back wall.  I've grown and harvested the Cumulus Amora and I'm not getting the option to level up.  So I checked my plants harvested list and according to that, I've only harvested four, when I know for a fact I've harvested six.  BUT the thing is that the same thing happened when I was trying to level up to 21, it told me that I needed to grow and harvest 4 plants, but I had already grown and harvested 4.   

I would ask support, as they can look into your garden with their magical ways and see what's been going on properly. :)
