Hi,
Yeah there are definite limits to what they can stand.
I lost these eggs the first time I tried substrateless because I used too flexible a mesh and they were sitting on far too wet a substrate for weeks before I noticed anything was wrong. :(

I tried cleaning and treating them but they all died in the end.
