If Max ever gets stuck in a "Rewind" where holding "R" for reverse or "Ctrl" for undoing an action does not work. Max will indicate that she cannot be in two places at the same time.

Note that this "bug" occurs mostly in Chapter 1 during the tutorial.

To fix this issue, follow the steps as indicated:
1. Press "Esc"
2. Select "Reload last checkpoint"
3. You'll have to endure through all the cut scenes again if any

Hope this helps! Cheers!
