I just checked the EEE-Sallega savegames.
The fact that the AI takes the basic (and not the bonus boosted) resource production into account when it decides about colony types leads to many interesting results (to put it mildly).
All those nice research and intelligence compounds abused for mining and refining while the empire already is buried under piles of ore...
This bug reduces any attempt of writing a bonus using AI to estimated guessing (not very estimated but lots of guessing).
Has anyone reported it to MM?
