Features disappear

[Y_Chau]

I loaded some survey data into an empty FC. The data appears fine. But when I close and open the project again the features are gone. Strangely the attribute table is there. Everything else is normal. Even exporting the layer to another gdb produces same result.

Any guesses where the problem is.

have you tried doing Create Feature Class then Make Feature Layer? I've had to do both when pulling from the portal to get the features to stay populated

Try this - go to your Layer Properties.  Click the Indexes tab on the left side of Layer Properties.  On the right side of Layer Properties, expand Spatial Index (if needed) and click Delete followed by Create.  Does the behavior persist?

If you loaded Survey quality data as a table, then most likely you then used the XY event mapping to show the data. To make the layer permanent you would need to save as a Feature Class.

If the layer is listed in the Legend Pane but is not displaying 'where' you expect, try right clicking on the layer and Zoom To to see where the data is actually being drawn. High probability that the layer projection for your data does not match of your base map. Again, convert to a FC to ensure the projection definition is saved.

*if this is actually survey grade date ensure you have the correct survey accurate  Projection Defined (e.g., NAD1983 (2001) vs. just NAD1983).
