A lot of the Civil NPC types say that their type does not earn wages according to the table, yet all Civil NPCs earn wages. Is this an error/bug or for a yet-to-be implemented feature?
Those that have no in-game purpose beyond RP (ie bartender etc) should not have a monthly pay requirement. Its possible that if they are showing as requiring it in the inventory pages, this is just a legacy bit and they won't require payment come the payment run at the end of the month.
However, it may be best to put it on the Bug Base just in case.
