structural and non structural upgrades

[hoarmurath]

My suggestion is pretty simple...

 

To make permanent upgrade slots only compatible with structural upgrades, while free slots would only be compatible with non structural upgrades

You mean like having (Default from the ship) as an example: Extra hammocks and Improved magazine access, and then being able to put something like, powder monkeys or marines?

[hoarmurath]

Yes, for example... Or reserving extra planking for permas, this kind of things.

 

The improved magazine acces and powder monkeys is a good example, as the magazine access should be part of the ship design, while the monkeys are crew members well trained for a specific task.
