Seems to be working fine now that I've upgraded to 12.1. I'll keep an eye out for 12.2. However, we are not using a before row update trigger. We are using an after insert trigger on the containers table though.

Ah, so you *are* using before-row update triggers. Almost certainly, this is the same bug fixed by commit 60e97d63e, so you should be okay if you update to 12.1. (There are some related issues that will be fixed in 12.2, due out next week.)
