If you impersonate a regular user, that is someone without access to admin/users, you’re dropped on the “the page you requested doesn’t exist or…” page. Which makes sense, as you no longer have access to that page (impersonate reloads admin/user/impersonated_user), but it looks like something went wrong when it happens.
Suggest as new landing page: impersonated user’s profile or the forum home page.
Minor issue due to most users not being admins and impersonate being (presumably/hopefully) an infrequently used function, just wanted to mention.
