Ok, so I looked around and if this has been discussed I don't see it. If someone knows a previous thread on this topic feel free to point me there, otherwise open for discussion. Been putting up with this for a while and have just really started getting sick of it... Here is my issue... Why does the alter refuse to mark some world maps? I usually collect some low level treasure maps from the guardian room in doom then go to the NPC mapmaker and buy 20 world maps. All bought together at the same time on the same facet from the same NPC, yet when I get to the alter and sacrifice the treasure map about half of the world maps yield the message "the location can not be marked on that map". What am I missing or is this just another bug?
