I'm not confusing the situation at all.
OP has an ALR with 3 days left on it and it's wearing thin and no longer scanning.
Mostly people suggested taking photos/copies of it just in case.
Some discussion happened about the practicality of reissuing an ALR from a ticket office, where we all established it wasn't technically possible due to the software (though you did posit that a supervisor may be able to sort something out), and there's no standard procedure for it.
OP confirmed they went to a ticket office and they ticket office said they can't do anything on the spot but they'll investigate and call OP later.
Some other discussion happened about PRT being a bit useless.
I pointed out that the contract the passenger has requires that, unless fraud is suspected, they be furnished with a new ticket. But also highlighted that practically speaking this might not be possible for a combination of the technical limitation previously discussed, and the practical uselessness of having a replacement posted out.
For some reason this was interpreted as meaning ticket office staff should issue replacements on the spot. Something which wasn't said.
@Watershed reiterated the point that while a ticket office may not be able to issue a replacement on the spot, it doesn't change the contractual obligation on the seller to replace it.
You then decided that I'd suggested going to a ticket office with an 'attitude' (I didn't), that staff won't know what the conditions of travel are (they will, but obviously won't have memorised the document), that I'd suggested asking the same question 200x (I didn't), that my advice of going to the ticket office to ask for help was 'incredibly bad advice' (despite it being what OP did and they receive a positive response with a potential future resolution), that I'd suggested going to a ticket office and claiming breach of contract (I didn't), that I'd suggested asking the same question 5 times (I didn't, but I suppose it's better than two hundred?), then agreeing that the resultant situation might be having to take a rail operator to court to get money back for a ticket which I have suggested is an awful position to leave a customer, and may even leave some customers not claiming money they're entitled to.
Except they actually did do this and received a positive response from staff who said they would look into it and call them back. That could well involve calling higher-ups for a resolution.
Please, stop misquoting me. I didn't say to go to a ticket office and ask for a reprint on the spot. It may be possible for the central ticketing team at the retailer to do it though. I said to go to a ticket office for assistance for a damaged ticket and ask for a replacement, but that doesn't mean expecting it on the spot. If they're able to reprint a backdated ticket, that's probably what a casual customer would expect, but I think we've all established this probably isn't possible.
Edit: I altered the last paragraph to make clear the difference between asking for a replacement ticket, and expecting one on-the-spot.
