Assuming anyone from the Dev Crew looks at this forum, here goes:

1) Once Numbat lures Jasper away from her office she never returns. This breaks a subsequent quest in which you are supposed to speak with her to ask her where to find someone she is looking for.
2) Djet is nowhere to be found in Koorda, nor is the Koorda library anywhere on the map. There is the one NPC Nmaamba, but nothing else there other than two wandering human figures with whom it is impossible to interact in any way.
