This is the second time this has happened to me so I'm posting it.

In Nation war I was flying a Valkyrie X-1 so a 3 port ship. I only mount 2 guns on it. One in the left and one in the right ports. The center port is left empty. After dying, clicking the buy back last ship rebuys the ship but fills up all the ports with the weapons. So rebuying my Valk with 2 neutron blaster actually ends up buying me 3 blasters.

Yah, I;ve noticed something similar recently too. I sometimes fly a corv maud with nt2 and ice flares. I sometimes also home in Sedina D-14, which does not sell ice flares, so I stock the station with them.

Months ago (sorry I cannot narrow it down to a particular update) what used to happen if I ran out of ice was it would stick a nt2 in the port that used to contain a flare, and leave the 3rd (but the usual port for my second nt2) empty, now it seems to fill the ship with whatever gun you had fitted if it cannot buy the secondary item, if it uses the same port.

I hope that makes sense when read back by someone who isnt me!

To try to describe it better:

My Setup: Corv Maud, Left S port nt2 - Middle S port ice flare - Right S port nt2.

(what used to happen)
On Buy Back(with no ice available): Left S port nt2 - Middle S port nt2 - Right S port EMPTY.

(what happens now)
On Buy Back(with no ice available): Left S port nt2 - Middle S port nt2 - Right S port nt2.

Which wastes my monies! It was better the way it happened before! But it might be better if it put the guns in the same slots they were in when bought back if a weapon is not available.

I got round this bug by using presets, but well, yah, its a bug.
