Nostalrius Begins - Quality wow vanilla realm (1.12)

I tried to complete the 2 escort quests in desolace : Gizelton caravan and Bodygard to hire.
Pretty sure i did everything well but nothing happens, are the quests bugged? If they are, is there a way to complete them anyway?

They've been completely broken since March.
