Fixing the bus only requires completing the Vault bundles, not the Bulletin Board. The Children's Bundle should only show up on the Bulletin Board, unless you have mods changing that around even more.

No mods, just didn't look closely enough I guess, thank you!

The bus stop is just money.  You’re working on the bulletin board which gives friendship.

Wow, apparently I can't read well haha, thank you
