So basically i was on stage 5 two days ago and then i completed my grind and then i realised that this game had reset me back to stage 4 after my daily grind! I have counted everyhting correctly, i have been grinding for 12 days and i have collected my event stages 12 days in a row. I feel so scammed after having to grind soo much and then fucking losing it for no reason.
This is definately a bug since i have been collecting the rewards for all of my stages and i made sure to complete the objective in times.
