I apologize for the inconvenience, that bug has already been fixed in version 0.2.2.
Here is a save from v0.2.0. Could you try loading it in your game? It may fix the bug.
On Android: /Android/data/aph.mcs.com/files/saves/
On Windows: Paste this on your File Explorer - %APPDATA%/RenPy/MCSimulator-1612844572
Be sure to make a backup of your other saves, as this one will take the place of the first slot.
