Easy crafy will make you finish your current scavenger quest. But it doesnt make you get all the recipes.
To be able to actually get the recipes just find a guide online on that "suddenly finished" scavenger hunt, and follow the guide to get all the items.
Same with main quest. If your main quest that required you to get a specific item suddenly finished when you use easy craft, just find a guide about that quest, follow it and get the item manually without the quest waypoint.
Been using easy craft since day one. It's not game breaking bug. No need to restart the game from scratch.
