I’m facing a strange behavior now: I tested the layerVersion plugin, at first it seemed to work fine and effectively bring back the previous polygon’s shape. But then a confusion appeared between the polygons : when moved one, it would ‘disappear’ and another would move as well and after saving this only the second polygon had moved while the first one would ‘re-appear’ at its original place. When selecting a polygon, 2 more ones are selected as well, and when deleting ‘them’ (with the red garbage can, I use QGis 2.8.2) the first one disappears only. This behavior continues after having uninstalled LayerVersion and restarted QGis.
Is this a bug generated by LayerVersion ? Has anybody seen this before ? My layer is provided by PostGis.
