I want my Magla Potions back, Louis

Currently doing the Skybound Avatar, having beat Zorba, I was basically drained of MP, and under the impression I’m about to lay the Royal Smackdown on Louis, I go and pop all of my limited Dragonsaps and Magla injections, and head in to fight him, only for him to immediately bugger off and the dungeon to end. Both my Hardsave and the Autosave put me after using all of them. I am beyond mad.
