People that played 1.0: Did the AI refuse to attack or occupy settlements as much as 5.2?

Does anyone here observe the AI over the endturn instead of fast forward?

They have a consistent reproducible behavior where the AI sacks a settlement with multiple armies in the vicinity and then runs away instead of occupying with one of the armies. They do this with no corruption, or heavy corruption, or no enemy armies in the vicinity.

When in the game did the AI become faux aggressive, when in reality the AI is very passive from what I have noticed? Was it always like this?
