I found a small bug yesterday.
If I have two buildings in queue to be built, and I buy one, the next run it CORRECTLY announces I built X and am now building Y (the next building in queue).
However, if I have only one building, buy it, and then place another building in queue, the next turn it INCORRECTLY tells me I built building X, and am now building NOTHING. If I check the planet though, it correctly shows the building being built, and shows that construction has already started.
