Send me your save file and I'll gladly take a look. There were some small bugs in v0.13 that have since been fixed. If you were playing the older version, it's possible that you've locked yourself out of doing the last couple of quests.
The save files can be found here:
PC: C:\Users\YourWindowsUserName\AppData\Roaming\RenPy\Lewd Town Adventures
Android: SD:/Android/data/com.{gamename}.program/files/saves Alternatively, you can use the file manager to find the correct save map where the Renpy save files belong.
Then you can send me a PM through Discord and I'll help you out.
