Gnus (nnimap) should synchronize which articles exists and which
doesn't when you enter the group.  Can you do (setq imap-log t) and
show us the logs from entering the group and selecting one article
that give that error?

Hm.  You didn't leave the summary buffer open on the first machine,
right?  You would have to actually quit the summary buffer, and then
re-generate it to make nnimap synchronize the flags.
