A step-by-step guide to re-producing this bug (optional):
Extra information (optional): I just checked my bag and I found that my 2 white scrolls are gone. I recall that yesterday I bought a sad mask and scrolled it with all 60% scrolls(I forgot there were 2 white scrolls in my bag and I had no intention to use white scrolls with these 60% scrolls). I did not get any warning while scrolling(if I did I definitely won't do that, the price of these 60% Face Avoid scrolls just doesn't deserve to use white scroll). I sincerely wish the staff member can help me out(maybe check the background data? sorry I am a computer noob, but if you guys can help that will be super appreciated).

 

Yeah I know there's a box, but I didn't get that warning yesterday(otherwise I won't scroll, I had no intention to consume WS on these 60% scrolls).

 

Alright, I gotta be careful next time
