Arcade EXP will decrease when you restart.
The 20:54 is already rolled back, and if you earn EXP (21:06) and restart it, it will be returned to a lower value than the first rollback (21:10).
You have already lost over 100,000 XP on rollbacks.
And it’s been over 6 hours since I first earned 500,000 EXP, but I never get milestone items.
I want you to fix this rollback immediately.
