The bug

When trying to load in the attached structure (revacraft.nbt) with a structure block, it will only get loaded in halfway, even though there are more blocks specified in the structure file.

Additionally, upon loading the structure, the server will log the following error:

Original description

i dont know if this is happening because, its a prerelease version but whenever i move my creation "Revacraft" with a structure block it creates this mess i hav 1 image to show what its suppose to look like

from what i kept getting.png is from what i got from a 1.13.2 version on the .nbt file

from original.png is to show what the front is suppose to look like

both proof to to show that i am doing it within the prerelease 5

and output to load proof is self-explanatory

Update: still getting these issues from the structure block but i have more bad news the output from load proof version of the error has pretty much not loaded most of the interior and from what i kept getting it has all the interior from the bottom half but as shown there is no top half, did structure blocks change in any way during the snapshots or prereleases?
