Description of Bug: My cups of ink are not considered full when I attempt to craft a book from the craft menu. Attempting to craft a book with another player dictating also gives me the text prompt 'You need a pen and a blank book to do that', but I think the issue may instead be with the ink. I tried with nine separate cups of ink pulled from a barrel.
Note that I have generally had nine bugged cups of ink that sometimes cannot be picked up and can suddenly be picked up a few hours later with no explanation and I did previously pour all nine cups into this barrel of ink; unfortunately I have no more individual cups to see if the next cup of ink works, and I can't move ink into inkwells because the inkwells disappear (see my inkwell bug report thread).
I don't think it's an issue with my nine cups (lmao) because I bought ink from someone else and the same bug is still happening with that ink
Reproduction Steps:
- Have a blank book, a pen, and a full cup of ink (mine was freshly made from a barrel), as well as some papercraft skill and at least one skill past novice
- Open craft menu
- Click a book in the menu
- See 0/1 full cups of ink memorized. Unlike past bugs which allow crafting despite this, this does not craft a book or move on to level selection.

Look description for the cup of ink, but it's what you'd expect a full cup of ink to look like
