Last reply row in admin page is not showing correct user

If I look at the tables, the last reply submitted by an admin has the timestamp 1391604588, but the last staff reply is timestamped at 1391575788, which is not in any of the replies listed as a timestamp.

The user is a site administrator.

I found the issue: you have a incoherent permission naming. Sometimes its called

manage_wpsc_support_tickets

and sometimes

manage_wpsct_support_tickets

This messes all permissions and user roles up.

Fixed this and others in pull request:

Yep, typos. Fixed in 4.2.0
