When copying outputs from a remote builder on a bad connection, and the connection drops midway, the entire build tree is aborted with "truncated NAR encountered", followed by "some outputs are unexpectedly invalid".

The actual error is fine - the connection did drop, and we can't recover from that; however, killing all the concurrently running builds is bad.
