[Q]

Thank you Daynarr. You just explained the odd behaviour I saw with the Borg race. They should only accept trade and research treaties, but when I monitored them (switched to human player and full AI on) they accepted even partnership. Because they have the logical bloodthirsty happiness type suddenly almost all planets where rioting without prior warning: they were angry about the treaties!
IMO the lack of the warning is another bug we should report to MM or what do you think?
