Congratulations @KatyJay88, that's quite an accomplishment! I know how frustrating and time consuming doing this can be, but fun! I have a collector Sim that has completed this too, but her collections are in a building on a Generic lot. It cuts down on the bills. :) Love how you organized them with the plaques. Smart! Leanne keeps her plaques in the bedroom.
My Sim didn't get all the special event collectibles though since they had already passed. I could've gotten them from debug I suppose, but meh... I don't have all the packs either, but she has every collection available to her. Anyway, Bravo! <3
