The 3.5 million zen is live!! And the glitch works on it too, I just popped the trophy.
Thank you @LucasDiasC for the glitch information and @Zenpai for telling about the new reward.
Stardew valley, easily one of the best indie games I have played this year. I 100% on steam, and sometimes I think of buying on PS4 to platinum but the minigame trophy is really challenging.
