No worries. There were no changes made so didn't have to indicate that. Appropriate credit I gave by giving the full asset file name containing the creator name and the name of the asset (as opposed to just the creator and asset name separately which would make it harder for you to find). And the link to the licence can be made 'in any reasonable manner' and that was done by naming the asset file, the page of which contains the licence (as you know because that's how you found it). Thanks.
