invasion... Plus closing at the exact time of it?

[Captain Jorden]

I think this is a little stupid but why do an invasion, when its closing at the time we start?

[Tiberius Fireskull]

As far as I know, the times (and places, most likely) of invasions are completely random throughout a day, although there probably is some limit. It was most likely coincidence that the two happened to overlap. It probably isn't on purpose, unless having an invasion while performing maintenance was important for some reason.
