There are actually quite a few it seems that aren't so afflicted by this. My collection of Zygo hybrids has grown but only one of mine so far is really troubled by this, even after having several outside for all if not part of the summer which means they go rained on and I don't dry the leaves afterwards. Most notably my Zygolum Rhein Moonlight does not have this problem. But I get why it bugs people.
