"redownload" if there was no download?

[v4hn]

Whenever an upstream maintainer decides to change the released tarball of a module and the user updated the module before, they will eventually end up with a "download skipped. File already present. Checksum failed." error during the next lin.

I'd like to propose to automatically try to download the module once in this situation.
Otherwise, if this happens in the middle of lunar renew, the module will not be updated but the update process just continues with the next module.

Comments?

Has the package manager a "pin to version package" implementation? If I understand the challenge correctly, I'm assuming that the user has set their own module in place, which is not easily perceived by the manager? Pinning may give it a mechanism to trust that everything is gravy(should there be no pinning is my current assumption).
