This normally happens because an enemy unit (often a barbarian) comes close by, and the AI "wakes" the worker unit so that you can move it away to avoid capture.I've accidentally pulled workers off their projects before they were done (still not sure how)

I'm very grateful for an improvement they made concerning that. I love the fact that units w/orders only execute them after your turn is completed. this stops the most annoying bug: I need to move my worker but he already spent his turn building a farm.
I had a city get the railroad bonus, even though the railway line it had a road hex between it (so the railroad was broken)
Also, you may not need to road up all your coastal cities if they connect from harbour. Go into strategy view and select trade routes you might see certain roads not highlighted meaning they are not being used to link the cities.
Of course, you may still want to use the roads for transport.
