# Unexpected Terrain Undo

## Description

When a user undoes terrain edits, terrain edits made by other users may be undone.

## Symptoms

When editing terrain collaboratively, you may see your edits revert to a previous state.

## Solution

While it is okay to use undo commands during collaborative terrain editing sessions, be aware that this behavior can occur.
