1. Create a singleplayer level at levels/single/a/mylevel.txt.
2. Play the level, win, and let the game save the replay at replays/solved/a/mylevel-YourName-CurrentTime.txt.
3. Outside the game, move the level to levels/single/b/mylevel.txt.
4. In the singleplayer browser, navigate to levels/single/b/ and highlight this level.
5. Click "Load Replay" in the singleplayer browser.
6. Load the replay from step 2.
7. During playback, interrupt, and win the level in a different way.
8. Let the game save this new solution.

Expeceted: Step 8 creates a file at replays/solved/b/mylevel-YourName-CurrentTime.txt because the level (against which we are replaying) sits in b/.

Observed: Step 8 creates a file at replays/solved/a/mylevel-YourName-CurrentTime.txt.

Speculation: This is because the game doesn't care where the singleplayer level came from, the game only cares about the level filename in the replay.
