Two AIs (random unrevealed). About 1:20 into the game we have an AIP of roughly 70-90 and kill a counterwave guardpost MK III (yeah, thanks King -.-). My homeplanet gets a 1000 ship warning as expected. About 3 minutes left of the timer, I get a 783(!) Bomber wave alert on my homeplanet and ANOTHER 1001(!!!) ships to the same planet, this time Deflector drones.
Attached savegame is mid-hilarity.
Is it supposed to be this brutal on 7.3-7.6? There was no way we could counter this on such short notice (3 minutes). The Mark III counterwave (1001 ships, assorted fighters, chameleons and stuff) was bad enough, but another 1800 ships on top of that was just nuts.
