The game has a few bugs. Some small and others big. Small as this or as the one which changes rank in campaign. Big as the bug that allows restart of campaign and is incredible that has not yet been solved.
Problem, however, I think is not what you see, because what you see, you can pretty much keep under control. Problem, for me, can be in what is not seen, maybe there is something, some error that prevents, for ex., that some players obtain certain items.
