When marking runes in Papua they say they are marked for Paupa. Don't think this is anything other then a "heh, look at that. It say's Paupa", but just in case the towns name has an impact on referencing between different codes and may cause potential future problems should a script decide to look for Papua and not be able to find it, I thought i'd go ahead and bring it up. Even though I'm sure it's treated as "flavor text" under the mark spell and has no impact on anything, better safe than sorry.
This is a known issue, it just requires editing of an xml file on the game server. I keep putting it off because I need to fix all of the classical UO areas so they show the correct rune marking also "Turtle Bay", etc. Thanks for the reminder.
