Thanks DarkStar! I appreciate it.
Second:
It's not really a bug because it's quite easily avoidable within the actual way the interface is supposed to function. In the example he gave, to assign no troops of a certain type to a domain in Domain Wars, just leave the square blank (which is the default). Blank square equals zero. Pretty easy, I think.
Though the docs don't make that totally clear, I admit.
In other words, it's not an unexpected bug that happens during the normal functioning of the game. It's an oversight that could be easily fixed, if need be.
And yes, if game-affecting bugs are found, I will absolutely fix them.
