Really? Shouldn't you actually need even more events? Considering it's currently not taking into account pausing the construction, workers being interrupted or killed by attackers, replacing dead builders with other peons and what ever else that I figured would come along with the random movement system from my impression after how Argos had explained it to me while I were making it months back.
Basically I've already made some in anticipation of that (the above), if it's actually not required for it to work properly, then I don't really have any complaints (Not that you would have to care about them to begin with.).
Regardless of what you do I'd be interested to know the change(s), as in if not the whole map at least see the relevant triggers, as initially I had not expected to use all those events either, but was shown otherwise, I'd obviously consider that you, like myself before, might not be able to do it as easily as you seem to think at the moment either.
edit: Rephrased and clarified some of my expressed thoughts, besides the obligatory grammar nazi I could spot.
