Grub update to reinstall the MBR part after "error symbol 'grub_calloc' not found"

I read all about [1] when it was in the news, and I was quite surprised yesterday that rebooting my freshly updated/updated Ubuntu 18.04 EC2 instance was stuck with the grub_calloc error (which I only found out after talking to level 2 Amazon support for a long time). Apt logs show Grub was updated to the correct version on Aug 3.

Shouldn't a high priority update be released that performs a one-shot re-install of the MBR part? There are likely many more machines with this problem. People are reporting them [2].
