Nanoframes that are constructed are not given to the previous owners should they be completed while they're afk. This has problems:
1.) What of the person who starts a nanoframe, goes afk at 1% and comes back at 99%? Sure this is not a huge ordeal for say a glaive, but expensive units are a huge sink.
2.) What about someone who goes afk at 50.0000000001% and returns when it's completed?
3.) What about someone who goes afk at 90% and comes back after its finished?
