FSPS normalizes the SED by the formed (initial) mass of the star particle and not the current mass. To take this into account changes were introduced in commit #150.
These changes are now added to nebular emission calculation as well. Specifically, the rate of ionizing photons (Q) is now calculated using the initial mass and not the current mass.
