During the prologue on the nautiloid, you aren't allowed to load the inventory of companions. However it turns out you can load it for a very small time frame by clicking on the level up button on the portrait. Since level 2 is reachable in the prologue, this exploit allows to make your companions drop items in their inventory before it is allowed later in the game. I haven't tested if it allows for other exploits like leveling up or dropping equipped items since the time frame is so hard to get right.
