for the gui to reopen

create a new game, save, quit , add or remove a mod then reload the save

the gui re-open but cant get more items from it.

ok, so what's happening is a security check.

When you change something the GUI appears again because if some items are removed from the quickstart bad things may happen.
I'll make it show the current quickstart and why the guy appears on screen but this is gonna take a bit.

I may make the GUI appear only if some items are removed from the quickstart but I still need to decide, I'm open to suggestions.

My idea is to change the blue arrow "Give quickstart" for a green one saying "Confirm Loadout".
Anything that let the player know that the state is different.

That's a great Idea I'm gonna do something similar or just that.
