Hi!
So Like the title says, it's a very minor thing, but does not seem to be reported yet.
So to reproduce it:
1) select an object in your toolbelt (you have it in hand with the ghost as cursor and the Icon in your toolbelt is orange)
2) save the game
3) reload the game : you still have the object in hand but the icon is now unselected.
Here you are Have a great day !
[18.X] Toolbelt Icon unselected at loading (very minor)
Re: [18.X] Toolbelt Icon unselected at loading (very minor)
This is acceptable simplification as quickbar selected slot index is not part of game state. You could have same item in multiple slots and it would not be possible to choose one particular slot based on cursor stack. I see no value added in chaging this. Same happens with GUI positions when you save-load: they will reset to default position.
