Tile improvements not finishing?

[Scorched_Earth]

In a game I'm playing now some of my tile improvements aren't finishing properly. I build a plantation or a farm and when the turns required to build it are up, the tile graphic updates and the workers stop working but the improvement isn't actually there. I've tried to rebuild it but it doesn't work. Has anybody else noticed this?

Did the workers get interrupted by a passing enemy unit (barbarian)? If so, that is intended - they "wake-up" to give you a chance to move them to prevent them being captured. Note that you are probably seeing the graphics for the "partially completed" improvements, and this can be a bit confusing.
