Custom Build Request Error

I am receiving this error for a Linksys EA8300 Custom Build for 23.05.3 that I have requested before:

Error: Impossible package selection...
Collected errors:

 * opkg_install_pkg: Checksum or size mismatch for package busybox. Either the opkg or the package index are corrupt. Try 'opkg update'.
 * opkg_install_cmd: Cannot install package busybox.
 * opkg_install_pkg: Checksum or size mismatch for package busybox. Either the opkg or the package index are corrupt. Try 'opkg update'.
 * opkg_install_cmd: Cannot install package busybox.
   make[2]: *** [Makefile:189: package_install] Error 255
   make[1]: *** [Makefile:154: _call_manifest] Error 2
   make: *** [Makefile:274: manifest] Error 2

I'm not sure where to report this so I'm reporting this here.

It looks like some temporary problem with mirrors syncing, try again in an hour or day.

Thanks for your reply but here's my problem. The Build Server seems to remember identical build requests. When I request the exact same build request, the server immediately replies in so many words: "yes, I tried that, here's your error message in case you don't remember the last time" If I vary the build request by adding an extra unneeded package, it builds just fine.

You can add whitespaces for start script to trigger new build
