EDIT

Murat:

I come across this error message when I add a new specimen to the matrix.
Do I have to reopen the matrix when I make this addition? In this case, the matrix opens very slowly due to the large dataset.

AM:

as far as I understand this error returns repeatedly. Did you recognize any pattern when it does occur? E.g. always when you add a new specimen to the matrix? Or always when working on a new taxon …?

Murat:

I got the following error message several times when I tried to save my recent works.
...
I always reopen the EDIT to fix the problem. However, this is not convenient because it opens too slow. It takes more than two minutes for each samples.
