I think I have a bug, either in the game itself or in the sell_equipment_1.3.oxp .
(oolite 1.73.4 on windows;
oxps : yah, asteroid storm, hawksound, pods, cargo_wreck_teaser, hyperradio, snoopers, and of course : snark.oxp )
With the Cobra3 from the beginning, I purchased 1 Cargo Bay extension, however my Cobra then had 50 T of cargo space. (should have been 20+15=35)
I was then (next planet) able to sell it twice - each time it took 10Credits fee and gave ~240 Credits for the sold Cargo bay each.
(so about 70 credits profit from bying / selling the CBE(s) alone)
But what bugs me more about it, is that even without any extra Cargo Bay, my Cobra3 still has 35 tons cargo space.

Is there a way I can like "edit" my Cobra to once again have its 20 TC ?
Anyone else had this faulty behaviour ?
