I Fixed the Kittens Won't Age Up Glitch!

Since it clearly wasn't a priority for EA, I took it upon myself to fix this infamous glitch! This glitch has been reported by hundreds of simmers for almost three months, but EA has done nothing about it, while I was able to fix it in under an hour. There's a download link in the description of my video!
