Error Code 500

Sometimes after marking image as complete everything seems to save but then a dialog box will appear stating that some objects cannot be saved with error code 500. Then if I switch to another image and back only one object is saved on the image. Has anyone else experienced this?

This seems to only happen to images that take several minutes to label

Dear user,
