Thank you for playing and giving feedback! I enjoyed playing your game as well (and so did my daughter!). When merging 2+ Selves, the highest value for each Facet is applied to the final Self, and the number of merged Selves is added to their production amount (indicated next to their name in the list when a Self has production > 1). So the only thing potentially lost is your ability to fill out slots since there are less bodies available.
