Yesterday, I was peacefully cruising and trading. I managed to buy me a Type-6, and got a 60-tonne cargo at Surya. When undocking, I noticed some cargo floating around, and I managed to pick up 2 of them. Then I flew to Chango and sold my 60 tonnes. Forgot about the scooped cargo, tho. A bit later, I arrived with a full load at Aulin, I used the docking computer to dock, I was scanned, and no 3 seconds later shot to pieces... 
Fortunately, I did not use all my money for the load, so I was able to buy back my ship and the mounted tech. This trip I did not make a plus
I wonder if there could be a marker somewhere that informs me that my hold is not empty yet. When I sell everything, maybe a red light in that vicinity to inform me that there is more to sell? Or a green light that show me when the hold is really empty?
