I apologize for necro'ing this thread, but I'm having the same issue. Not sure if the functionality went away with the new career system or what. But I just started playing around out in Atlantis and this is just one of the things that isn't working for me (combining scrolls into books). I haven't been able to start ML's nor have any artifacts dropped, so I have a feeling Atlantis is one of the last areas to work on. TIA for any advice or places to look for this functionality.
