@coolsim9999999 Hey no worries! I've always got half a dozen or so saves on the go where I play around with things.
What I find interesting is that not all those saves will experience the same bugs.
For example in three of my saves the dance floors make no impact on build mode at all. In another the perk points for groups do not disappear. In another again all the male townies spawn in with the super thin female eyebrows and the feminine walk and are over weight, in another this doesn't happen at all. In one file the perfect garnish/toppings combo works on my sim in another it doesn't even though it is the same sim. The list goes on. I find this weirdly fascinating.
