Can you try the v0.33.2.3 that just got released for free? This bug is supposed to be fixed there
It's really hard to replicate this issue on our end. Any chance you could upload your save file (for example Mega or LimeWire), so we could take a closer look and fix it?
Saves on Android are stored in either:
1. SD:/Android/data/[something with academy in it]/files/saves/
2. [Your local storage]/Documents/RenPy_Saves/[something with academy in it]
