When shift clicking worker actions (an amazingly cool feature BTW) at some point, the game decides that you let go of shift early and the worker proceeds to his first task, deselected. This is not consistent but does happen about 75% of the time. On occation, I can queue up as many actions as I wish, as it should be.
Edit: Oh forgot to mention, since 1.52, the worker options when holding down shift, sometimes don't appear. This didn't occure previously. e.g. the square the worker is moving to doesn't have the build options for that square in the list.
