/etc/mkinitcpio.d/linux.preset getting blown away after yay -Syu

Sometimes seemingly randomly when I run yay -Syu, successfully update and power off, my /boot/initramfs-linux.img is gone. It appears that the linux.preset file in /etc/mkinitcpio.d is empty? The fix is relatively simple, boot the arch live iso, copy a backup linux.preset to /etc/mkinitcpio.d, run pacman -S linux and then everything is fine.

It's happened twice on my laptop in the last couple months and this morning on my desktop. I wrote a little system update script to guard against it happening again, but does anyone know what could cause this?

#!/usr/bin/bash

yay -Syu --noconfirm

if [ -f /boot/initramfs-linux.img ] && [ -f /boot/vmlinuz-linux ]; then
    echo "boot looks good"
    exit
fi

echo "Restoring boot"
sudo cp /boot/linux.preset /etc/mkinitcpio.d
sudo pacman -S --noconfirm linux
sudo locale-gen

if [ -f /boot/initramfs-linux.img ] && [ -f /boot/vmlinuz-linux ]; then
    echo "boot recovered"
else
    while true 
    do
        echo "*** boot still broken!!!!"
        sleep 1
    done
fi

What is the output of

pacman -Qkk mkinitcpio

Here is the output from my laptop which has exhibited this behaviour twice.
