what is the expected behavior when the gem was yanked from rubygems?

[AlexVKO]

Today the version 0.3.5 of mimemagic was yanked from RubyGems, but the version is cached on our gemstash instance.

I'd expected that it would not break the current fetching, because I can see the gem inside the gemstash directory.

Is that something expected?

Your bundle is locked to mimemagic (0.3.5), but that version could not be found
in any of the sources listed in your Gemfile. If you haven't changed sources,
that means the author of mimemagic (0.3.5) has removed it. You'll need to update
your bundle to a version other than mimemagic (0.3.5) that hasn't been removed
in order to install.
