<div dir="auto">Hi,<div dir="auto"><br></div><div dir="auto">You are missing one of the most important aspects of QGIS (and most GIS software): The data is independent of the project.</div><div dir="auto"><br></div><div dir="auto">The project > save action saves the project, which include what layers you have loaded, what order you gave them, their styles, and so on.</div><div dir="auto"><br></div><div dir="auto">When you edit vector layers, you need to use the save icon in the digitising toolbar, the one next to pencil icon that you have probably clicked to start editing. This is done layer by layer.</div><div dir="auto"><br></div><div dir="auto">Best regards,</div><div dir="auto"><br></div><div dir="auto">Alexandre Neto</div><div dir="auto">QGIS Support</div><div dir="auto"><a href="http://www.qcooperative.net">www.qcooperative.net</a></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">A sexta, 8/10/2021, 17:17, Firstname Lastname <<a href="mailto:byron@conjugategeo.com">byron@conjugategeo.com</a>> escreveu:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br clear="all"><div>i have saved several times. this i know to be true because i have been importing maps and georeferencing several times. i have saved these maps as i have been working and the imported maps have saved. the problem is that i have been digitizing polygons for several days and recently qgis crashed on me. the polygons disappeared that i have been digitizing but the geoereferenced maps have been saved. the polygon layers were all saved and were not scratch layers. can anyone help me to understand why the polygons did not get saved. </div><div>i am certain that i have saved dozens of times using Project/save.</div><div>i am reluctant to do any more work if i can not be certain that it is saving</div>-- <br><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr">Byron Veilleux, MSc.
