Ars Nouveau's Touch+Break spell needs to be shift-clicked to break most containers - in most use cases, while this often still opens the container, the UI is immediately closed as the container is broken and its contents are handled appropriately. With Quark crates the contents pop out as they should, but so does a copy of the crate itself while the original crate block remains. Projectile+Break works fine, so it looks like an issue with the crate being opened and broken at the same time. I'd post this on Ars Nouveau, but it works properly with every other container I've come across.
