Description

When a contraption that has a lectern attached is moved, it looks like the book data is somehow invalidated or deleted. When I attempt to open the lectern, which visually still has a book in it, the UI for it briefly opens, then immediately closes. Breaking the lectern doesn't drop the book. When clicking the lectern, there is nothing printed to the log on server nor client.

This appears to have started to become an issue when we updated to Create 0.3.1b, as this didn't occur in 0.3e.

Just a light hunch, but maybe Tschipp/CarryOn#292 is somehow related?

Issue should now be fixed in dev branch, thank you for the report!

technical summary - contraption placement nbt handler maintains has_book: true property, but removes Book compound nbt that contains the book and the book's nbt data.
