Someone posted a lot of stickers in trades for someone to stick them. I did it for them right away as soon as they accepted and they are messaging me saying they can't find them and never got the achievement and I don't want them thinking I stole their stickers ..Is there a way for a mod to find out what happened and show that I did stick them because I am not sure if there was a glitch or they just don't see them..this happened about a week ago or so no one else has complained

Users' sticker albums are public, have you tried going to theirs to see for yourself if the stickers you added are there? If they don't have the information on their profile you can plug their ID in here, the only other thing I can think of is that you misspelled their name/missed a letter copying and pasting or something and there happened to be another user with that name that got them instead

No I didn't pay attention to them just stuck them as I did everyone else's and I was careful and kept looking at their name to make sure the name is Spiderwebby so it was fairly easy to remember anyway..how do you plug an ID?

ok Thank you
