Describe the bug

When I paste a schematic with API using both FAST reorder mode and fast mode, pasting works but I get the following exception during session flush:

To Reproduce

Here is the code I used to paste the schematic. All works perfectly with WorldEdit 7.1.0

try (ClipboardReader reader = format.getReader(new FileInputStream(loadFile))) {
	Clipboard clipboard = reader.read();
	ClipboardHolder holder = new ClipboardHolder(clipboard);
	BukkitWorld bukkitWorld = new BukkitWorld(ars.getWorld());

	final EditSession editSession = worldEdit.getEditSessionFactory().getEditSession(bukkitWorld, size);
	editSession.setReorderMode(EditSession.ReorderMode.FAST);
	editSession.setFastMode(true);
	BlockVector3 to = BlockVector3.at(loc.getX(), loc.getY(), loc.getZ());
	Operation operation=holder.createPaste(editSession)
			.to(to)
			.ignoreAirBlocks(false)
			.build();
	Operations.completeLegacy(operation);
	editSession.flushSession();
}

Expected behavior

Normal pasting
