I apologize, the mod is broken – I rushed when uploading it and didn't package it properly. The NoBlockEditor.PAK file is lost, which is why the objects aren't displayed in the map editor. I don't even know where to get it. If I come up with something, I'll let you know.

Guys, there's a file in the archive called NoBlockEditor22.03.2014.h5u; rename it to NoBlockEditor.PAK, and it should work. In my haste, I didn't enter the old name and accidentally added the map extension. Let me know if the mod works.
