A hotfix for a quests-menu crash, a sweep of the same crash across several other menus, and a fix for companion mods that read your MMO skill data.

  • Fixed: the Quests menu could disconnect you the moment it opened. On a server with quest categories, opening the Quests menu could drop you at the loading screen ("Disconnected from server. CustomUI Set command couldn't set value"). The category tab buttons are fixed.
  • Fixed: the same disconnect (or a button showing a raw "{0}") on several other menus. We audited every menu and fixed the same issue wherever a name or amount appeared on a clickable button: the mastery "Pay with" buttons, the Token Shop and Bounty Board offer lists, the leaderboard skill filter, your tracked-achievement list, the new-player tutorial preview, and some admin pages. Most of these only bit servers that add custom skills or content. Bonus: the admin skill pickers and leaderboard filter are now translated instead of always English.
  • Fixed: companion mods that read your MMO skill data could log an error at startup and lose their integration. Mods like Perfect Parries that read your skills through the MMO no longer print a NoSuchMethodException when the server boots, and their MMO-powered features work again. (The 1.4.0 localization change had removed a method they look up.)
