creatures keep their first corner, and characters never share files

- a creature walking a path no longer cuts its first corner: the path's first waypoint was dropped at decode (2342)
- two characters whose names differ only in accented or non-Latin letters no longer share macros, bindings and SavedVariables; a file that failed to load is not overwritten at logout (2342)
- custom chat channels survive a logout, a collapsed quest header keeps its quests watched, and a trackpad swipe scrolls as far as it adds up to (2342)
- a hearth off a zeppelin no longer lands back on its deck, and an opened lockbox with loot left in it unlocks (2342)
- every snapshot runs on Vulkan, in a container, before it ships (2344)
