In other streams the AI does build up its planets. It probably won't be ideal; and I can see the AI having massive issues with balancing its economy and with the strategic resources (that are required for advanced tech). That stuff is problematic even for players with a lot of deficits and fluctuations. But it doesn't always just sit on empty planets
In one way, that is not good news.
Bugs which lead to total across the board failure tend to be easier to fix than those that only rare their head in certain circumstances. The former is usually just caused some silly mistake easily fixed (DEBUG_ALWAYS_FUCK_UP_ECONOMY set to true or something daft), whereas the latter can mean your entire approach needs a rethink and at the very least you're in for a few hours/days trying working through the code.
If every streamer is experiencing the same issue, the AI just doesn't build enough resources to develop planets/build fleets across the board then I think it will be fixed in the release. It may even have specific to that one build. If, on the other hand, the AI only fucks up its economy some of the time there's no way they're getting a fix for that out by Thursday. On the other hand, it will be less detrimental to play, depending on how frequently the bug appears
