Missing blocks after pasting

Parts of the build are simply not there — a wall with gaps in it, missing stairs, a roof with holes. The rest of the structure is fine. This is not a corrupted download; it is the game deciding it does not know what those blocks are and leaving air instead.

• The game version is older than the build. A block added in a later update does not exist in your version, so there is nothing to place. This is by far the most common cause.
• The schematic was saved in an old format. Files from the 1.12 era store blocks as numeric IDs, and modern WorldEdit has to guess at them. Some guesses come out as air.
• The build uses blocks from a mod or a plugin that you do not have installed.
• The paste hit the world height limit. Anything above the ceiling is discarded silently.

1. 1Check the map's page for the versions it lists, and open the world on one of them. Matching the version fixes this outright in most cases.
2. 2If you are pasting a schematic, make sure WorldEdit is current. Old conversion code is a common source of gaps.
3. 3Paste at a lower Y level if the build is tall and you were near the ceiling.
4. 4Still missing blocks on the right version? Write to us with the map name and a screenshot — that is a problem with the file, and we will fix or replace it.
