I have requested the traffic order as something may turn up (or not, which would be even better).
Don't worry about the discount, as long as the council received formal representations against the Notice to Owner within 14 days of the date of issue, they'll re-offer the discount anyway, so there's little risk in carrying on.
The only thing you need to do at this stage is double check that the address on the V5C is 100% up to date.
