Yep, they can be divas, those phals. Mine are all outside year 'round, and they love the cool weather, but seem to hate the transitions. Right now they're all in bloom and about half of them are putting on the wrinkly leaves just a bit.
I've learned not to worry about it, they seem to recover just fine given time. In fact I have yet to murder one, although it's been close with a couple.
