My Changes Are Missing

Work in livediagram is saved automatically as you go, so missing changes are usually hiding rather than gone: you may be looking at a different tab, a different diagram, or a different identity than the one you edited under. This checklist walks through finding them and, where needed, recovering them from history.

First, find them

1. Check the right tab. Each tab stores its own content. If a tab looks empty, confirm you are on the tab you actually edited. See tabs.
2. Check the right diagram. It is easy to have two similar diagrams open. Open your diagrams and confirm you are in the one you edited.
3. Check the right identity. Guest work is tied to the browser that made it. If you switched browsers, switched devices, or signed in, you are looking at a different owner's set of diagrams. See working as a guest.
4. Reload the page. A refresh reloads your saved diagram and clears any temporary display issue.

How saving works

Changes are saved automatically after you make them, per tab, to the server, not just to your browser. There is no manual "save" to forget. Because saving is per tab, editing one tab never disturbs another, and an empty, never-loaded tab is prevented from overwriting a tab that still has content.

If you edited offline or on a flaky connection, a save may not have reached the server. Reconnect, make sure the diagram is loaded, and let the autosave run again.

Recover from history

If a specific change was undone, reverted, or overwritten, the Activity Panel is your recovery tool.

1. Open the Activity Panel. It lists recent edits on the current tab, newest first, with who made each one.
2. Find the change you are missing in the list.
3. Revert an entry to roll that specific change back, surgically, without disturbing other people's unrelated edits.
4. Use Undo and Redo in the panel for the most recent steps.

What collaboration does and doesn't protect

Two people editing different elements on the same tab is safe. Edits travel as changes to individual elements and merge by element, so your move of one box cannot overwrite somebody's edit to another. That was not always true, and it is the single most common shape of "my change vanished".

Two people editing the same element is the case to know about. There the last edit to arrive wins. In practice the editor heads this off by showing an element as locked while somebody else has it selected, so you can see that it is spoken for before you start.

If a connection drops, the editor catches up on reconnect rather than reloading: it asks for what it missed and applies it. Your viewport, your selection and your undo history survive, so a wobbly connection no longer costs you your place. If it has been away too long to catch up, it re-fetches the diagram, still without a page reload.

If you have checked the right tab, diagram, and identity, reloaded, and cannot find the change in the Activity Panel, contact us with the diagram URL and roughly when you made the edit.
