Server Implementation

Paper

Server Version

1.20

Describe the bug

When editing a large area and undoing this editing action right after it is possible that the world is not correctly restored.

This happens with fast-placement: true as well as with fast-placement: false.

The severity of the lost blocks seems to fluctuate as most of my tests only had some missing blocks but one of my earlier tests have had a 3-8 block wide hole. The length of the holes also seems to fluctuate as you can see in the attached pictures.

To Reproduce

1. Create a fresh server/world
2. Teleport to ocean to see errors more easily
3. Execute //sphere air 400
4. Execute //undo
5. Search for error in the world

Expected behaviour

The world should be returned to its original state without any modifications or missing blocks.

Fawe Debugpaste

Fawe Version

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?

All of the above pictures were taken in different worlds. After most of my tests i stopped the server and deleted the world folder and/or the FAWE folder to get reproducible results.
