I use [Userscript]: Double-Check (Version 2.x) to give myself another chance or mark as correct when I know I’m right or super close – but that my wording was slightly different or my answer not in the WK whitelist (of course I have to be extra careful I’m not accepting answers that have a different meaning or nuance).
I think I made the same mistake as you at some point @BosS_MaarioS, and while many Americans might think it outrageous, I don’t know which US cities have states with the same name etc and am not particularly interested in learning that information right now 
So I probably marked it correct and moved on. I add synonyms after I’ve done this more than twice on a word (because sometimes I’ll also type it exactly how WK wants it).
