Even when nothing is produced (canceled menu) the "hammer" sound is still played.
Seems like this is the case only for Carver's workbench.
I've fixed this issue.
Nope. Still there. Now there is no sound if press ESC directly in the "first menu" when selecting the type of production, but there is still sound when selecting the exact item to produce.
But now it should work.
No new reports for over a month. I will close this for now.
