Natural Living Skill

While playing the event yesterday in with a brand new sim my skill for natural Living reset. I had played for hours building the skill all the way to level 7 just for it to be taken away and all my progress ruined. I know exactly when it happened, my sim stayed the night in a park and then went to Willow Creek to "view the tree" for the event quest. As soon as I entered Sylvan Glade I was reset to level 1 of only the natural living skill. I haven't played in months and just wanted to do the event and get some goodies but no. Every time I try things are ruined. I hate it here. Also, I play on console so it's not any kind of mods, it's the game.
