I'm not sure if this is intentional as the new format for Kumos/New Wardrobe, and is just not implemented yet, but when attempting to go to a User's page from their CW shop or even any User linked by them (Say, in the shop description to give credit for banners and such), it redirects to a page called https://subeta.net/user/*UserName* which is a 404. It seems an "s" was omitted from the "users" part of the link, unless the new format is going to use the singular form of "users".

Also, attempting to preview posts before submitting them right now seems to freeze the page, necessitating a refresh, at least on legacy, and may potentially wipe/delete a post if the poster hasn't Ctrl+C'd beforehand, as a friend in my comments made me aware.
