And what if the original fix was item-based, and mine is the same solution, but adapted to weidu? Is it derivative work when the solution for the same bug is handled completely differently? And can anyone hold the right to write a single byte in an item?
Those are some weird ethical questions by which I mean to say the version 3, which is up now, adapts multiple bugfixes from various people, fixes an internal bug, and restores some forgotten spells (optionally.)
