I might be in trouble

That's great that you found something that works for you but I fail to see how a plastic light diffuser could have anything to do with your eggs going bad. It also isn't very helpful to say because if he removes the light diffuser it will have no impact at this time unless his mix isn't right and then removing the light diffuser will actually kill his eggs.

Since well, just because.....
If the mud is damp enough they will absorb moisture though the skin.
Problem is that its too early for them to be that dry and the egg can harden to a point that cutting will be to only option to salvage any that make it to full term.
They can start to mold and the move can also kill them or agitate them enough that they may tangle their cords.
Its a gamble either way at this stage.
