Hello. Katy!
When I copied the nvl screen into a new RenPy game (along with the nvl_faded transform) It will only show the first line of dialogue, and when clicked a second time, the first line of dialogue will fade as intended but then none of the other lines of dialogue will appear. Why may that be?
Thank you for the clarification. Since the issue is persisting, I would recommend starting with the framework's script setup and adding (pasting in) your visual novel's custom scripts around it, rather than the other way around. This would help to avoid missing any lines of script that are being left out through the transfer.
