hey there developer. i've just played your game and i got to say your game is really amazing. but i just encounter an issue regarding saving serena mission. you see, right now, i'm in a mission where i should go to the portal made by the foxgirl at the shrine in order to save serena and i've done it.
but then here comes the issue. after that mission, the story ask me to get the water crystal located at mortimor tower (tower in the snow location) and i did it. the problem is, when i tried to talk to the foxgirl, instead of continue on with the water crystal, the mission where she opened the portal (the same portal in the previous mission which is used to save serena) again and the mission reset back to save serena eventhough i've done it. heck! even the main character (ada was it?) even said that she doesn't has business when i tried to enter the portal inside the cultist lair.
i don't know if it's happen to only me or not. i play the game with joiplay and i kind of mess with the item (the only thing i mess is adding herbs and item required for construction and nothing else). but i don't really think that would be the case.
