@Lavendela91 It should be in your family inventory, like a previous poster said - that's accessible in buy mode if you haven't poked around much. All kinds of zany things, occasionally including plants after I've been building basements, wind up in there.
But yeah, mostly here to say that I, too, have won multiple fair competitions with no completion (and I have checked to make sure there's not just a check-in requirement it's not updating in the description by talking to the assigner too - for me that's the grocery deliverer).
Also having the same issue another person reported about the signature drink quest - and yes, I will go to that thread, as I have also gone to the thread on how, if you have this expansion, you can't interact with the rocket to build it. At least with that last one there was a mod that fixed it - but seriously, for things that have been known issues for this long, it's pretty frustrating that EA hasn't fixed these many bugs yet - and that despite "not supporting" mods and generally putting up a lot of scare text to discourage their use, on at least one occasion so far a mod has been my only recourse to fix a bug they should be on top of.
Time to go write some reviews, it seems, if this is what the norm for bug mixes has become from this company.
