Right, I am slightly worried. I opened QGIS this morning to discover that part of the work I did yesterday was not there (the attributes where present in the table, but were not digitised anywhere on the interface). I had assumed that I had accidentally done something last night before I went home that caused this to happen.
So I thought, not to worry, it won't take long to re-digitise the lost polygons. I finished the work, produced the map and saved the project so that I could close QGIS and was very worried to see that of my 13 polygons, only four are left! This has happened simultaneously with two layers (the two layers show the same boundary but the polygons are subdivided in one of the layers).
Is there any way I can undo, this/fix this. Whilst I should have finished with the layer, it is not beyond the realms of possibility that I will be asked to make minor changes etc.
