omg! icedoll !1!!11!1! aftegay

ChocoPie_isme

wtf is this shit

Sydneory Z

@ChocoPie_isme an error dont watch this
ArrayList.kt

Litely

you
//8chars

Azure

did you just copy this from another client?

Sydneory Z

@Azure huh, it does not same for the other client just visual

Azure1

I mean, you copied the code from another client?

Aftery

the average thread iq is going down

? Offline

@chocopie_isme its a code as you can see
