You may try to talk with puppet and see if you've done every task of every animatronic, if you did, then just wait for new version
Uhh idk then
Like the the springtrapppy has only one quest with the voice module and the dialogue about golden freddy
Mangle is basically fixing her and fighting the endoskeletons (ofc there's an option to craft some upgrades for her)
The bonnie's,chica's and freddy's quests are connected so you def will complete each one of them
Foxy quests are coins and maintenance
And the puppets quests finishes after the basement adventures
So there's no more new content need to wait for update, maybe if you'd explain what you meant i could help but well ┐( ∵ )┌
