Stand by! Twiddling bits and adjusting levels

Ok so I just typed a massive update to one of my items and I get this nonsense (see the picture).

The message just hangs forever.

This has happened to me NUMEROUS times on Tindie and I am extremely frustrated by this. All the typing is gone and I have to start all over again.

Tindie fix your sloppy code please!!!
There is no excuse for this. When I sell an item, I physically test every single one.
OBVIOUSLY the person(s) writing the code on this website does not feel the need to test.
