XML: Crafting Progress (or lack thereof) in custom CraftingPhaseStagingSuperInteraction

I'm making a writing notebook (the pen-and-paper kind) based on writing interactions from computers; I had to clone them all since I'm using teen homework animations. Everything's working so far except for one crucial bit: the progress bar/circle for writing books doesn't update while the staging interaction is running, and the crafting process never finishes. Non-craftable writing (love letters, excuse notes) works fine, progress bar and all, so I guess something is wrong with either the recipes or the staging .. but I cannot figure out what the problem is since the statistics and craftables aren't changed =/.

Writing the same books on computers works fine (updates and finishes properly), so it wouldn't be an issue with my game or my sims I think.

Any ideas on what I could be missing? This is pure XML tuning so far; is there anything related to crafting interactions that would need an edited DATA file as well?

I've uploaded the raw XML here, can provide the package as well if that would be helpful.


ETA, a preliminary version (without the crafting stuff, just the object with Practice Writing and other time-based interactions) is available here.
