Wasn't AI supposed to act like they have supply range?

[Wizzington]

They ignore supply range when invading, respect it when blockading and fleet hunting.

If they didn't ignore supply range when invading Europe would never be able to send troops to East Asia, for one.

Austria probably shouldn't invade Ethiopia in this case, but not because of supply range. Mind you, a player could do what they're doing without much difficulty by just buying some fleet basing rights.

 

[Wizzington]

How about a compromise? Some kind of interests check for whether they have some kind of a wargoal outside supply range?

This way a nation would not break supply range logic unless it had a reason.

That sounds sensible.

Incorrect.

The AI will occasionally leave its fleet in place after dropping off units. I have seen German states drop troops in Mexico and leave the navy on the exact sea zone used to drop them.

That has the feel of a bug rather than something you intended, since it prevents them from getting more units and makes their fleet a sitting duck, but it absolutely does result in them blockading a province 100's to 1000's of range past their supply range for extended periods.

That is indeed a bug.
