you seem to have an issue with a milestone that was on a cc that you removed from the game.
Try this mod: https://www.patreon.com/posts/mod-milestone-81237568 (File 2: CC/Mod Object Fix).
This should fix the Sim.
I am confused. And I know your super busy! Please, if you will, help me understand this. You wrote "you seem to have an issue with a milestone that was on a cc that you removed from the game." The item in question was the placemat from the Storybrook Nursery kit. or not???
Which then my mind is questioning if the items in the Storybrook Nursery kit are actually cc or is it that the game identifies it as cc? or either? I don't have the kit yet.
I no longer get any packs until I know what bugs are in them and if I want to deal with that issue(s) or not. I never used nor ever will use cc or mod so I am confused greatly by what I am reading here.... I have spent, now many hours just reading all (and I do mean all and I am not done) the bugs on your (read first list, which I go through monthly) so the likes will disappear when I start looking them over again in the future as I use those to keep track of what I have read already. I do thank you for your help!!
