Imaginary Friends Not Coming in Mail

[Axiom]

Ever since I installed Seasons, my Imaginary Friends stopped arriving in the mail [I understand that its a 75% chance of getting one]. I have no idea why, since everything else from Generations installed properly [I also had to do a complete reinstall right after installing Seasons, due to a serious Riverview glitch]. I've also had no Aliens since installing Seasons.

I've had 4-5 kids born since the reinstall, so its either the odds or something gone wrong.

I have the following Mods, all from Nraas:
NoCD
Overwatch
Tempest
ErrorTrap
StoryProgression [And the Fairies/Werewolves/Vampires submod]
MasterController [And the cheats]

And then from ModtheSims:
NoIntro
NoBuildSparkles

I thought I'd list these just in case.
Help?

Aliens and IFs aren't guaranteed.  I only get IFs for every fourth birth these days and I almost never see aliens unless I'm actively looking for through the telescope and picking up space rocks every day.  Although I did have an alien show up in the middle of the day instead of the middle of the night just this past week.

I know but I used to get them a lot more before installing Seasons.
