[FIXED] [GRO] Milestones reset for uncontrolled sim who is visited/invited etc.

I still have the issue of milestones disappearing. I play with 2 different families and I lose my milestones not only when I actively visit the first/second family, but also, for example, when I use my first family and I invite Sims of the second family and then I switch to the second family, the Sim of the second family that has been invitated has lost the milestones. I also noticed that if you remove a family from your active families and then you readd it, also in this case all the milestones reset. I think that it's a very complex issue and it's very complicated to figure out when milestones resetting and disappearing will take place. Now I gave up and so I'm continuing to play rotationally even if I know that at some points my milestones will disappear but for sure this bug need to be solved, because unless you do play rotationally, it's a pity to lose one of the most important features of Growing together!
