Hello
- The change "sda -> sdg -> sdX" is not a problem, it is due to the BIOS.
- The message "Linux not detected by os-prober on sda2. Please report this message to <email address hidden>" is just informative.
The real bug is:
os-prober fails to detect the /boot partition of Arch in sda1.
As you say that Arch was correctly detected before doing update-grub, I think this is a regression of os-prober.

My 2 cents.
