Describe the bug

We tried to replicate #2104 with same schematic as given in the issue, but also we stumbled upon an different error.

To Reproduce

1. Replicate the situation given in #2104
2. Deactivate "send before history" in config as @SirYwell recommended to us
3. Paste schematic and //undo it after the chat message says, it is done

Expected behaviour

No exceptions in console, everything should be fine (except the issue we replicated)

Fawe Version

FastAsyncWorldEdit-381

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?

No response

Not sure that this is a replicable issue and I think it could be just a random "it just happened the once"...? Unless someone else has had this/you've had it since

Yeah, but has anyone actually been able to replicate it since?

If you can reproduce this stacktrace, it is for sure

I am also having this issue on purpur 1.19.3, I paste a schematic inside some terrain and then try //undo, and it leaves horizontal lines of blocks.
