Isekai: Waifu Overlord: Game Is Stuck in Tutorial Screen (Workarounds)
Short answer
Suggested fix (unconfirmed): Reply to the thread asking the developers to reset your in-game progress. Wait for them to clear your save data so you can restart the tutorial.
The problem
My game is stuck in Nyakol screen "Sympathy" button cannot be pressed cause it's locked but it's the only option. Please just reset my progress maybe.
