Got it - I'll check up on the book bug and should have it fixed by the next build! If you copy-paste your current save files somewhere safe, & then paste it back INTO the Saves folder on the upcoming build, you SHOULD be able to use the same save this time around on the new build!
And thanks for the heads-up on the text box bug too! Does it stay permanently onscreen if you talk to someone & then exit out? (edit: tested this myself and found the answer, lol. On it!)
