I have created a world for a server, more precisely a schematic file, and if one inserts it, and then places Gravel somewhere to fall down, he bugs away, where he should actually be then is "immovable, invisible "bug block".
I have used the latest Worldedit version and insert Async Worldedit.
I had that too. Have it via WorldEdit (not the plugin, but the software!) So the structure loaded and set. The prbolem did not occur. Try it while you shut down the server to avoid problems
Can you give me the download link?

maybe you have to look at it as a tutorial, the program is a little advanced.
But I want to insert the schematic at a precise coordinate.
Can you?
You can then move on with it or teleport to players that are pinned in the world file. It's a second Minecraft, but it's completely self-contained. There's also a player, but only to look around, etc.
