UCAS did a weird thing

So here is the situation; friend of mine has applied for all straight law courses. He has received three out of 5 decisions. Out of those 3, UCL was not one of them, but it was almost. Now brace yourself because here is where this story gets worth it enough for me to hop onto TSR and ask you guys for any insight. For context, I will tell you this occurrence took place the day before we broke off for the Xmas half term, and there was an email said friend received prompting him to check UCAS as there was a change to his account (it was a rejection from one of his choices, not UCL). Alright, we are in school, it is the day before our Saturday leading into Xmas half-term, friend checks email to see UCAS wants him to log on, he sees the rejection, but also sees from the notifications that he has received a UCL offer. He taps on the offer, it is conditional and etc, typical offer format and is from UCL. Excited, tells friends, runs off to tell teachers but before he does, shows me the offer too, and I see the conditions he needs to meet etc. Runs off to let the world know, comes back, refreshes page, the offer is gone. Where before, his UCAS page read '4/5 offers recieved, UCL offer made for law, conditions as listed', the entire offer just disappeared. For more context, no correspondence was made from UCL about a congrats for the offer. Friend's hopes got crushed in a matter of seconds and FYI, these events unfolded in the span of 5 minutes.
Anywho, anyone got any insights on what on earth was or is going on? Is it a case of UCL refrained from sending out the offer before Xmas, UCAS mixed up offer-sent systems. Spitballing here, don't have a clue about the inner workings of the system. But yeah, thats the situation. Quite bizarre.

I don't know why we didn't think to check portico. Yeah I'll go ahead and tell my friend to do that too, as well as contact ucl. Thanks again!
