Checklist

• I have included a Fawe debugpaste.
• I am using the newest build from https://ci.athion.net/job/FastAsyncWorldEdit/ and the issue still persists.

Anything else?

I think i don't use properly the methods but really can't find a way to make it work

Are you attempting to undo multiple schematics that were pasted at the same location/overlapping?

Well, no. Here is a record of what's happening. With the delete command, the method UndoMultipleSchematic is called for only 1.

Ah, I missed that you've got the editsessions in EditSessions#undo the wrong way round. You'll also want to do each undo asynchronously, and could use a task that re-schedules itself whilst an iterator over the editsessions is not empty

I'm sorry but i don't really understand how i am supposed to undo with my new EditSession.
I just set the BukkitRunnable to run async and it did not changed anything : my schematic is still here.

For the iterator, yeah, you're right, i'll take a look at it when my undo method will work !

You have the editsessions the wrong way round. You're attempting to undo the new editsession using the old one. The javadoc notes for the method explain this.

Oh okay ! I really didn't understood it like that.
If someone is confused as i was, i had to simply switch my editsessions and do :

try (EditSession editSession = WorldEdit.getInstance().newEditSession(current.getWorld())) {
    current.undo(editSession);
}
