Oh No! You did not pick a valid target! not on all users but its happened twice so far

Are you completely sure you're spelling the username right? I copy + paste my friend's UN and I haven't had a problem.

Make sure that you didn't leave a space before the username.It happens sometimes when you copy/paste.

so do i

Then you're probably leaving a space or something like said

ok will try again

Did you get it to work?

yes i stopped copy & pasting

ok locking as resolved :)
