Re: Missing my last turducken leg...

I found my answer!

Per Breakluna over at mut.gg:

"I think the 'missing' leg would be from house rules. My understanding is that there was a window of time during the first day or so of it being live where some players were not receiving harvest house rules rewards. To make up for this, it seems EA gave everyone any house rules rewards they earned during that time period regardless of if they were missing the rewards. My guess is that you earned the hungry harvest player and the first turdurken leg from house rules during this window but not the second leg.

It's unfortunate that you can't fully upgrade the fourth player but you're technically not missing anything as you're only supposed to be able to get three full turduckens and three hungry harvest players."
