Crested gecko: Only one egg laid

[LSeelt]

In one of my breeding groups I had a unique situation occur. My male passed away from a prolapsed hemipene, but did pass on his genetics, and I got two healthy eggs. The following month, my female laid two eggs, but one one made it (the other died a few days later).

This month, my female has laid only one egg. There is plantation soil lining the bottom of her enclosure but it dries out really fast, and after all this trouble it has caused I plan on moving back to paper towel substrate. I also have a moist deep lay box in there that all my females in my other breeding groups tend to prefer. She chose to lay in a dry area. The eggs is yellow-ish and dented, so I'm predicting that it won't be viable, but I incubate until it molds just in case (I have seen dented yellow-ish eggs come back and grow).

Should I be concerned that she only laid one egg? Could she be bound with the other one? Any idea why she would choose the dryier spot, as it is right next to the lay box? If these eggs (this egg) does turn out to be a dud, should I pair her with a different male this season, or is there still hope that she can lay viable eggs from her pairing with my male who passed away, or should I just let her live out this season, and try again with her next?

All input is really appreciated.

if she has another egg, it should be visible or at least palpable.

I have heard of a clutch laid up to a week apart? I would watch her for signs of illness (lethargy, etc) and palpate her gently.
