I put both BUG and SUGGESTION because I'm not sure if this is intended.
I built a scout and put him on autoexplore. I went to the options and enabled Auto End Turn. Everything played the way I expected. Then, I went to move the scout to cancel the autoexplore. At this point, the scout continued to autoexplore and after each movement, my turn would end. The game started playing itself, essentially. I had to fight through dialogue boxes to the Auto End Turn option to shut it off and stop the scout from moving like that.
Nothing stopped his movement. Not the research screen, design, build screen, or anything except checking off the Auto End Turn option. The camera kept snapping to the scout, as I expect it was supposed to do.
Something tells me that isn't intended. I believe that the game isn't disabling autoexplore on the scout and than "thinks" that I moved the scout, thus, ending the turn. It then goes into an endless cycle of no fun.
If nothing occurs in a turn, I don't think it should automatically end.
