I tried mods for the first time, and it was working just fine until I installed one from Kawaii Stacie, and then all mods stopped working. Every time I install aa Zipped File, it does not work or show up in game. It was odd too because I uninstalled it and the other ones worked fine but then as soon as I uninstalled them to see what was working and reinstalled them, they didn't work. Ever since, my keyboard has been glitching and being odd in/during the game. I do understand that I downloaded the mods at my own risk, I was just seeing if you guys had any recommendations or if you guys knew of anything I could do about this. I also tried to repair my game and that didn't work as well. I even tried to see if all mods were up to date, and they were. 

Thank you so much!
