"sequence chain" fails after chain lengthened

[ym337@…]

The following bug report has been submitted:
Platform:        Linux-3.10.0-1062.9.1.el7.x86_64-x86_64-with-centos-7.7.1908-Core
ChimeraX Version: 0.92 (2020-03-08)
Description
I was using ISOLDE to model the protein. However, I just noticed that I am not even able to save the session and I am getting this error message (screenshot attached).

Hi Yaikhomba,

I see this is essentially the same problem you reported 8 days ago (ticket #2919). It's not easy for me to reproduce, since I would have to learn how to use ISOLDE to lengthen a chain, and then hope that's enough to actually reproduce the issue.
If that script I sent you allows you save a session, could you send the session to me so I will have something that reproduces the problem so I can work on it? If you don't want it part of this quasi-public ticket, you could send it directly to me in email. My email should accept large attachments.
