I had a battle where my Champion went to level 2 so I could chose which of the 5 paths he should follow.
After the fight my turn was over (playing with auto-turn) and it was one of those generating an autosave.
When I reloaded the autosave (because I actually wanted to take a look at all the paths, first game) my champion was level 2, but neither had a path selected nor could I choose one for him.
Seems to be some problem with the order of, auto turn end <-> autosave <-> champion path select popping up in another turn and isn't triggered again when loading.
