Resetting inventory in Gedel Escape

Let me remind you that the player's main enemy is time. Every time a planetary cycle ends on Gödel, everything in the inventory disappears. Exception: things that are in protected slots (there are 5 of them and they are highlighted in gray). In the video attached, at the end of the cycle, the fat block disappears from the inventory, and other things that remain in place in the protective slots.
