lol I keep looking at the title to this thread post like someone's calling my name, "Huh? My comics Oops, are you talking to me?" 
I do the occasional grammar and misspelling. English (even though I speak it and live in America) isn't my strongest subject.
I've also accidentally misnumbered my pages before and scared my readers that they were missing a page of the story. lol
And a few times, I've forgotten to fill Oops' triangle patches on his cheeks black. (They glow white when he's about to do a magical blast)
All of these have been fixed the moment I've spotted them, hopefully, I've found them all.
