Thank you for the feedback, @Synoxys787. To everyone: I’ve created a separate thread for discussing the mod so that this thread can stay dedicated to the bug report and sharing data related to it. Here is a link to the mod thread.
I’ve included a suggestion in the initial post for anyone else who runs into the same problem with the layout.json that Synoxys ran into. If anyone is interested in trying the mod, I encourage you to use the new thread to continue the discussion!
