There's a bug that some people cannot send characters to collect junk (see e.g. here and [?permalink=99649#comm-99649 here]). EA will fix this.

In contrast to what the anonymous user stated in the second post, this is a permanent addition and not an event, there is no rush. You can either wait for that fix or contact EA, which might help to raise the priority or a bugfix.
