Starting Poimt - Archetype: Submitting Flag Issue

Just to preempt any who might say I haven’t looked for this problem, I just want to say that I did do a 10 minute search (which is more than one should in an organized forum) and didn’t find anything that solved the problem for me.

With that said, here’s the problem: the flag I found (I used the walk-through of course) isn’t being accepted. I submit HTB{b…8} and get the reply "wrong flag submitted."

This is obviously some kind of error that’s not on my end, so I just wanted to put this out there for one and hopefully get a reply back from someone stating why that is.

Thank you in advance.
