When saving a shp file object, the object is lost.

[kralalala]

What is the bug or the crash?

When saving a shp file object, the object is lost.
The number of objects before and after saving is the same, but the object shape is lost. If you look at the picture, green is the original object, and red is the object after saving. I didn't do anything else, I just modified the contents of the field and saved it, but that happens. Is there a solution?

*Original object

*Objects after saving

*before and after comparison

When I put the shp file in the cad, this error occurs.

@kralalala, could you please provide the layer, attaching it to this issue report as zipped file or as an URL to download it?

@agiudiceandrea

This is the original shp file of the layer where the error occurred
layer.zip

@kralalala, I've imported the layer in QGIS 3.28.5 and then exported it using the "Save Vector Layer as..." dialog (via layer context menu "Export"->"Save Features As..." or main menu "Layer"->"Save As...") and it seems to me the exported layer contains the same features and it is visually identical to the original layer

Could you please describe in details the exact steps needed in order for the issue to occur?

Could you please specify all the info requested in the issue report form (e.g. the content of the Help->About window).

I may be wrong but looks like @kralalala did not provide the original layer (the green one in his top message)

[agiudiceandrea]

Thanks @DelazJ, I didn't noticed it.
@kralalala, please provide the original layer and describe in details the exact steps needed in order for the issue to occur and specify all the info requested in the issue report form (e.g. the content of the Help->About window).

@agiudiceandrea

The result of modifying and saving some contents of the field in the green layer is the red layer.
An error occurred when saving. So there's no existing green layer.
When saving, you saved the existing layer as it was, not as an export under a different name. (I saved it as a blue circle in the picture below.)

Normally, there is no error when saving. However, sometimes when saving after a job, the object disappears like that. So I posted it in the question because I thought I could find a problem in the error file.

@kralalala thanks for reporting the issue. I'm sorry the original file has been corrupted. Could you please specify the content of the QGIS Help->About window in order to know which Operative System QGIS is running on and which GDAL version QGIS is using in your system?

[agiudiceandrea]

@kralalala it seems the Shapefile index file has been mostly corrupted. Find attached a repaired version of your layer with all but 1 the original features and with only some feature geometry with incorrect vertices. Hopefully it will help you to restore your data.

@agiudiceandrea

QGIS GDAL version is this.

Thank you for your help in restoring the data.

Could you tell me how to restore it?

@kralalala is ytour shapefile stored in a folder which is synced by some cloud provider, e.g. dropbox?
