Ok, I see, we need to maintain only 1 single design per ship class. but this doesn't seem to work either.
I just ran a quick test game, and, if I do not manually edit designs at all the auto upgrade works just fine, but if I make only 1 custom design the AI won't upgrade anything, not even its own designs. (I need to click "Auto upgrade selected design" for each design each time)
empire policy is set to auto upgrade, and all designs are set to auto.
Ok I see the point, If player makes its own destroyer then the AI will continue to upgrade all designs except destroyers.
Even if there is only one player made destroyer design (with refit off), the AI will ignore destroyers completely.
thank you for clarifying!
