Playing single player with the latest build, when I shift clicked the grout recipe out of the Forestry work table, the quest log did not count the crafts as completed. Later on when making the seared brick blocks, clicking them out of the crafting interface one at a time double counted them in the quest book (counted each craft as 4 items crafted when the recipe actually yields 2 per craft). I haven't noticed this problem with any other crafting operations, but not a lot of quests call for crafting of a large number of items. Most bulk item quests are retrieval.
I'm able to get around this because I figured out how to edit the quest book (after losing a ton of progress to a problem not related to the mod pack), but especially the shift clicking not counting could definitely cause some pain for players. The simplest solution may be to simply change the tasks for the smeltery quest to be retrieval instead of crafting, at least until a proper solution can be found.
