Capitalization of area name.

When you have your map open and you click the Aetheryte for Leynode Mnemo, it says "leynode mnemo" in all lowercase.

Yeah, all the aetherytes in Living Memory are like that, and it does look odd.

I noticed this too. It's strange that Leynode Mnemo is capitalized everywhere else... On the map, when you mouse over it, in the list of teleport destinations, and the teleport offer notification all have it as "Leynode Mnemo," but the dialogue box to accept the teleport had "leynode mnemo" instead, which threw me for a loop. I wish there was a little more consistency (like if it's supposed to be lowercase, it should be lowercase in the teleport list and notification, too, in my opinion)

This is another case of FFXIV using title case for certain things and sentence case for others. Leynodes, like aetherytes, are not capitalised naturally. Similar things happen with "the outskirts" outside of the Everkeep. It's just the English localisation using title case for toast/notifications/menus/name text, and sentence case for, well, sentences. I think they use title case too much personally. I would much rather Things kept natural sentence case structure most of the time.
