Bug in Skirmish mode

I am running it on a macbook pro 13" from 2010 with 8 GB of ram and a 2.7 GHz Intel Core i7.

There is a bug in Skirmish mode that causes units to not be produced. After clicking the button to produce the unit, I get the message that the unit is being produced and get the message that the unit has been produced, but the unit is nowhere to be found. The population count also does not change, so I am quite sure that it is a bug.
