Reward is gone :(

My first mistake in this app is picking Girl X Battle as my first go-to quest to complete (never knew they have a policy of removing quests) My second mistake is pay a little in this game to speed up the progress, which in the end was pointless as the quest is gone and I earn not even a cent back of what I invested. This kind of game for sure will take at least a month to complete for its quest, no idea why it was removed early, perhaps I was the late one here.
