Did you open up the internal membranes to see if there was excess liquid in there? Late deaths are usually due to humidity issues, with humidity having been either too high or too low throughout the first 18 days.

I turned the humidity down to 40 yesterday. Ive tested my humidity seperately from the rcom thinking maybe that is it but it tested out fine. I had it at 49 before yesterday. I am in missouri and its been raining for 2 weeks(90%humidity) so maybe atmospheric humidity got me somewhere in there.
