Comment 2 for bug 1627326

Do you have a savegame that you could upload to this bug?

As far as I can tell from the screenshot, the productivity of the building is still at 100% - messages for Lumberjack's huts only get sent if the productivity drops below 66%.

The tooltip at the building tells you that the lumberjack didn't find a tree the last time he was looking for one. It should return to normal the first time he finds a tree again - if that doesn't happen, it's a bug.
