[NOT A BUG] City unit production fail

[bc1]

G&K, all DLC, latest patch
City was producing archer, while an archer was already in the city.
City was mostly surrounded by enemies (but there was at least one free adjacent tile).
When production is complete, no new archer appears (and unit list shows only a single archer).

Do you have a save from just before the the production completes? Thanks!

Went back to look at the saved game: the only free spot was a mountain.
My apologies for this erroneous report, could a mod please delete this thread ?
