Those aren’t actual errors - the message indicates that those faulty YBNs are fixed at runtime, and 99% of the time those messages are not indicative of any issues. That said, if one gets stuck on 0% collision preloading, you do need to have that person check their F8 (or logs) to see if they have any clues as to what is causing it.
If you cant find a fix you can try dealing with the invalid YBNs, I will shamelessly plug my own guide on the matter:
