Quite easily, Emma speaks to the house too late, they prompt Emma to reveal too late, the housemate takes too long to leave the house (more of a problem due to them really) - or sometimes just a simple matter of them not properly timing the show or not realising when the adverts start. Just human error really. Given it cut off just after Wolfy left the house I would assume they messed something up earlier on (probably the announcement of who's safe).

I can't remember what show ITV did it with, I swear it was X-Factor or a live show like that.
