Does the AI still rebuild stuff?

[Traveller]

Playing against a mine-heavy AI in my current game, I've never seen the AI rebuild stuff.  I know five years ago they used to have rebuilders, and that was a reason to have cleanup drones...but I've never needed those cleanup drones myself.

Is that feature no longer implemented?  Are cleanup drones useless?

Negative, no rebuilding by the AI in the current game.  I think cleanup drones may be able to clean up un-broken AI mines, but given how they'll get shot down while trying to do so, they're not much help.  Not unless you don't plan on capturing the planet, but do plan on moving stuff through it that isn't mine immune.
