Okay, I ran tests on the following mods from this
thread:
AlienPregnancyFemaleEnabled: Works. Got pregnant every time
RandomAlienPregnancyEnabled (random male/female pregnancy): Works. Got pregnant after the 3rd abduction. This applies to both male and female Sims
RandomAlienPregnancyFemaleOnly: Works. Got pregnant after the 4th abduction.
Do NOT use GetAbductedEnabled or GetAbductedEnabledCollection or GetAbductedEnabled&Random. None of these mods work for both FT and AL. These mods are unnecessary since you could use a Abduction Odds mod or similarly named mod from TJ, Carrigon or someone else. My Sim got abducted at least once per night using TJ's Higher Abduction Odds mod.
You just had a streak of bad luck with your Sim not getting pregnant. Keep trying.
Thread is now closed. If you still continue to have a problem with any of the mods I mentioned in
bold, please open an inquiry in the Mod Help Section.
