the other day i had an explorer supposed to return... instead it sat at a full progress bar - then when i clicked him to see how long he had it was at -39, -18, and so forth - when it got to 0 it would reverse back to -60 and so forth... i waited 3 min for his return (when he was already supposed to be done) and refreshed etc.. nada... i gave up and logged out for the night -- meaning i couldn't send him out for his overnight search - he was finally back to 'normal' so to speak the next morning.
