We understand where the confusion is coming from.
In Project Kat, the language selection menu was not removed. In Paper Lily Chapter 1, the language selection menu never existed, because it was not translated to other languages yet. Nothing was removed.
To translate Paper Lily, you need the translation files. For Chapter 1, we didn't send out those files yet - this is because we anticipated a large number of changes for v1.1.0. We didn't want translators to have to work twice.
Rest assured, we will send out the translation files soon. Thank you for your understanding.
