Once again wormholers strike my colonies! This time it's GJ 1002, the hub system between Zemlya and Altair, where homeworld of Wedgefield stands. There are 5 long-range missile PDC which could strike the attackers...
...
If I hadn't forgotten to bring some missiles here. Main fleet is stationed somewhere in Altair (3 systems away!), QRF is kind of destroyed (or "under reconstruction"), and attack here was really unexpected, because all but one system linked to GJ 1002 are populated.
Lives of 120 million people are at stake because I'm forgetful.
I will scramble some outdated ships and, uh, start taking notes? Or maybe field meson PDCs instead? But they can't cover civvies...
Ruling a 20-system empire is hard, and it's only a matter of time before combination of small mistakes will lead to big failure.
