NL 12.3.0
1. Activate the option to save auto replays of solutions (on by default).
2. Play and solve a level.
3. In the postview screen, click left for the next map.
4. In the preview screen, press arrow-left to return to the map from step 2.
5. Click to enter the map.
6. This replays the solution from 2.
7. In the postview screen, click left for the next map.
8. In the preview screen, hit ESC several times to exit NL.
Look in the replay-autosave dir. The newest 2 replays are identical text files.
Expected: Game doesn't save a replay if this has already been saved.
Bonus report of what works: This bug does not hit when (step 2: playing the map manually) is replaced with (step 2': load an already-saved solving replay and let it run to the end). The game doesn't save any files at all during 1-2'-3-4-5-6-7-8. This is good.
