Community Edition makes it twice as costly to close doors than stock, but it is also more difficult than stock overall. I don't remember doors autoclosing. I think it's just aliens prefer to pay the cost of closing because it only used to take 6 TUs in stock. It's also really easy to change. DoorOpenAp and DoorCloseAp in the config will change cost for player and aliens. Don't forget LargeOpen and LargeClose. I used to be working on a big mod but never finished it. My AI was kind of a nightmare because aliens would not stay out of cover.

well doorOpenAp doesn't solve the problem i set those to 20 and the alien can still open it fire semi auto turn around fire a shoot turn around and either he STILL has ap to close the door or it DOES close automaticly ( i did ALSO change largeopen and largeClose)

Doors on alien ships are auto closing at end of alien turn! It works this way on CE. And as I recall, it was the same on base game.

Doors on location (human doors) don't autoclose.

the ability for alien to pop out from their door shoot and then have the door close behind them
?

This can be mitigated by not opening door in first place, If you are not planning to storm in. then Aliens would have to come close and open it, causing reaction fire of your troops.
