My Mod restores them, after the EA bug removes them. So, your sim loses their custom pronouns. Because EA has a bug in which if a sim changes CAS gender in live mode (= gains / loses breasts), the game changes the sim’s pronouns to those traditionally associated with a gender binary.
NOTE: Top surgery sends the Sim to CAS afterwards (you’ll see a window informing you).There are 3 possible scar styles (swatches) so not all sims will have the same! Download MonoChaos’s “FtM Surgery Scars” HERE If a player downloads their file for it, my mod will auto-apply the scars to sims who had top surgery. MonoChaos made (optional) Top Surgery scars to go with this mod!
