Yes, this bug introduced from the 2Gbyte Update:
You can always vote to show the mods and the community, if you has issue with the last stable release.
Well there was no stable update, since above 30 days. Atleast for me i saw only a Firefox update in this time. Are you using a auto update function in Pamac, maybe you can disable this, so you know when you manually click update and archive the full control.
To disable Auto Updates makes sence, because in this case you can manually create a backup/snapshot with timeshift and you are prepared if you get a unsolved and heavily error from a bigger kernel update.
