MarsSeed [1] filed a deletion request for mcedit-unified [2]: The Python2 based MCEdit Unified tool is dead since 2018 and fails to build and run. [a] The project's website recommends the new 'spiritual successor' utility called Amulet Editor (AmuletMC), which, unlike MCEdit-U, works with the new MineCraft 1.13+ level DB as well as the legacy database format.
