Edit:
Put everything I had into new ships, lost the game within 5 minutes. This is impossible :(

Have I missed an update that affects outposts combat power? Initially (?) they have zero contrary to vanilla Stellaris. Is this a bug or intended behavior?

Edit 2:
About the outposts:
This happens as far as I can tell only in the mirror universe and only to the Vulcans (have not played all races yet). Seems to be a bug, then?

Might want to add your difficulty...
