1.20 BUG Can't upgrade/modify captured ship - Causes negative missile capacity

[Xenon472]

Hi everyone, I wanted to report a annoying bug I just encoutered:
I captured a Selene sentinel (L paranid ship) and ordered it to dock to the argon shipyard, the first bug was that if I replaced all the missile turrets it had a negative missile capacity, and even selling all consumable missiles, I couldn't complete the order because it had this negative missile capacity.
I tried to undock and dock again and the problem got worst, now whatever change I make when I press "add to shopping list" the immage goes black but it remain stuck at the modification page, with on the left the components (engine turrets etc) and on the right the " currently editing"
And I can't confirm the order because it say in yellow "currently edited ship not added to shopping list"
Has anyone else encountered this bug?

Update:
it got worst
Now it does the same thing with every L ship I try to update at the shipyard, even with the one that worked fine earlier xD

Using a save from before the issues started, see if things have improved in the next build 1.21 due out soon {tm}. Aspects of this issue are addressed in there.

I'm on 1.21 and having the same issue. When I try to click add to shopping cart on my L Mining ship it unselects the ship and the screen goes black. So I can't use my new ship because I forgot to install shields when I bought it. Hope they fix this soon.
