What do you get when you say "get kingLiberated" in the CLI?
If it is "false", try "set kingLiberated=true" and then visit your bookshelf in the campground.
General question: do your tomes, etc., become available in Bad Moon as soon as you free the king, or do they depend on recalling your skills? The code as written assumes the former...
Edit: the Wiki says this:
- The bookshelf is not affected by Hardcore or Ronin restrictions. However, it is not visible while in Bad Moon, although it is currently possible to access the bookshelf through direct linking. Originally it was possible to use the books normally to cast spells this way, but this was soon fixed.
- Books can be placed on your bookshelf while in Bad Moon, although it is not possible to cast the spells they grant until you have ascended under another moon sign.
So, in other words, while you are in Bad Moon, we cannot visit the bookshelf and therefore cannot learn what books you have. We could "directly link" to look at it, but the Campground code, as written, doesn't bother; it only looks at the bookshelf if it can see it.
And the Wiki, in several places, says that you cannot cast book spells in Bad Moon even after freeing the king. Recalling Ancient Memories recalls your skills - and now your familiars - but I see nothing to indicate it gives access to hidden campground stuff, like the Bookcase or the Telescope.
