I notice that from time to time i lose turrets , scanners and even shield on my tranposrt akegata. Same happnes eith other vessels too. I figure it is interconnected with cargo allowance. Somehow the weight of equip is not always counted in balast so when i fill up ship he randomly discard some equipment from time to time.
I noticed too that if i load my tranposrt full it will DC me from planet and console will report cheating. So i always load 10 cargo less and that solve problem . But in space you always tractor something on the way and thats where equip is randomly lost.
