Crested Gecko - Only one egg?

I have a crested gecko who is new to laying. She's of healthy size (stays consistent at 25g, good eater on pangea though no live insects), is 3 years old and is a virgin female that I do not plan on breeding. She laid her first clutch a month ago, two eggs that were well formed, but a bit on the soft side which didn't surprise me since it was her first ones. This time around she only laid one that was much more calcified and perfectly shaped. She did rebury it (she's in a bioactive tank). It was a day or two ago that she laid. I'm worried about the fact that she only laid one; is this a common occurrence in new egg layers? Obviously I should be watchful of possible egg binding, but I'm not really sure what to look for. I don't typically bother her much, she's very very flighty.

I forgot to mention that she was recently moved to this tank, about two weeks ago. Getting her out of her tank to handle her is relatively traumatic, she hates being handled and obviously I had to do that to move her! Maybe she's a little stressed?
