HELP! I TPed to a place that must not exist and now I crash at sign on

I TPed to a sandbox, earlier and as soon as I got here it went black. IT then froze and I can't push anything to tp out or preferences or world tab to tp home...I've logged off and on and because I respawn in last location I can't get out of this non world place, wherever it is, one of those public sandboxes for building. It is like it isn;t land at all.

What can I do?

At your log -in screen press Ctrl+P and in the Preference panel under the General tab at the top there will be a drop down menu that will allow you to choose to log in to either your last location or your home location or a SLurl. Set it to Home Location and you should be ok.

I love you!! Thank you!! Worked like a charm
