Is it known that when you hover "Craft" next to recipe name in the alchemy screen you get "In Bag: 0" for any type of bomb? It's correct in other screens (chest and backpack).
The following happened when a save game that was made with version 0.49 is opened with 0.48. Sorry. (Maybe there should be an explicit warning that the savegame incompatible?)
BTW: When I switch from the chest screen to the backpack screen I get an exception and the game crashes with
Exception: DynamicImage u'[kazdy_element.icon]': could not find image. (u'ic erotic book')
EDIT: Happens any time when I open the backpack, obviously when I bought the book in NorthCrest.
