when entering an instance from a hub (Fortuna, Cetus, Necralisk) there is a chance you will enter unarmed and will have to manually swap to a weapon, upon swapping to a weapon your abilities will cost zero energy. this bug will persist until you enter the simulacrum or swap frames, upon swapping back to the bugged frame without entering the simulacrum prior to loading into a star chart node your abilities will still cost zero energy.
