Finishing a mission gets me back to 'before the mission'

After Battle reloads autosave from end of battle before

So have had this a number of times now. I finish a battle (usually haven defence, last was Syn not sure if all are) and when i go back to the geoscape its loaded the autosave from the end of the last battle. So im in Geo some time before i even started the battle i finished. Very annoying
