There were 8 records in the recipe book as shown on this shot.
Then I read 3 books and new 5 recipes were added. Should be 13 total, but recipe book shows only 12. Look next 2 shots. Scroll to the end doesn't reveal all recipes.
"Imbue with Poison" is missing. Should be easy fix. Possibly check array boundary.
No recipes from the beginning. Bought these 3 recipes from Elenaise:
1. Healer Yohan's Guide for Healing;
2. Eyes of the Direlynx;
3. Helpful Potions for Mages.
Five recipes appeared in recipe book. Then traveled to "Farrock caves. Level 1" and read 3 recipes from 3 tables. Imbuing ones. So eight records total in recipe book as shown on 1st shot.
Then bought 3 recipes from Harpen:
1. Toughen Thy Skin;
2. Breakfast of Champions;
3. Curing Greater Ailments
Log told that 5 new recipes were added. Indeed. But "Imbue with poison" disappeared. No such record even if to scroll recipe book the most down. Possibly scroll is buggy - it should allow to scroll one more position down. Or maybe array sorting lost one item.
Update
I tried to read "Imbue with poison" recipe from table again, but log tells "This recipe is already in your recipe book". So assumption, that scrolling is buggy, is more probable. Anyways, this bug is minor. I still can imbue with poison knowing ingredients.
Update 2
Read another recipe "Stumpy's Guide to Combustibles". Another record appeared in recipe book, but no "Imbue with poison".
