1-8 Stacking achievement not rewarded despite fulfilling the right conditions

[torn summit]

Hello! I was checking out the new achievements and trying to get them one by one, I came across the 1-8 stacking achievement and tried to get it. Despite having fulfilled it multiple times, the achievement still doesn't get rewarded. I made sure to attempt it and get the right run without any mistakes because I thought it might be a skill issue of me getting random clears without noticing

oh, i thought the condition was to clear 40 lines with 10 quads on column 2 or 9, does that include not stacking over them?

i mean, the quad just wasn't in that column right

if you placed it in col 1 then took the quad in col 2 it would've worked

oh true

welp, that was kinda dumb of me, i'll try doing it again in column 2 only

deleting the thread when it works
