I've been playing trying to get the game to crash, but it isn't cooperating. But I did notice a weird issue with upgrading my ships. When I click upgrade in the ship designer, the important parts that I would want to upgrade (like weapons & defense) are missing. There's a space for them in the boxes, but I can't select it to remove it. Clicking on the part on the 3D model doesn't work either.
Also, obsolete upgrade components are still present in the parts list. If I have a smaller, cheaper and more powerful laser, I really don't want to see every laser I've ever had available. I mean, what's the point? It's clutter.
When upgrading ships in space, weird things happen. I would launch two ships I made, and then move one aside so I could click & upgrade it. But the other ship would get the upgrade. On top of this, it looks like the name of the ship didn't change to the upgraded model.
