Bomb recipes disappear. (The Witcher 3: Wild Hunt)

You probably want to ask the question are bombs finite or infinite? In this case, I will tell you that your bombs are replenished after meditation, therefore, the recipe disappears, you no longer need it, you made a bomb for the rest of the game, you will replenish it by meditation, that's all

Real Slim Shady
I meditate, and bombs are current 1 pc. appear, but you need 2

Improved bob recipes add bombs incrementally
