Save itself is fine, it's just a problem with Tia in the village. I tried it both ways: old save, when Tia is already in the village and old save when you have Tia but decide to leave her in the village in the new version of the game. Tia gets stuck in the village in both ways. Basically, in the new version of the game the dialogue where Tia asks to accompany you after you leave her in the village doesn't activate.It shouldn’t break the saves but be just a bug, since Chyos polished Rumah’s time table and also this version is still a test version not completed.
But give us your save to check anyways.
How to give you my save, just post it here as attachment or PM you?
