I feel your pain, Wanapasaki. Sounds like an honest mistake and while it is your responsibility in the end, I would be super pissed at your buddy.
A few weeks ago I was waaaay out in the sticks archery hunting elk. I was glassing on a ridge and a F&G officer rolled up, which I could hardly believe given how far I was. Anyhow, we had a pleasant conversation and he asked to check my tag and license, which I promptly produced. Much to my shock, he told me I didn't have an archery declaration. Long story short, when I had my license reprinted, the shop forgot to include it even though I clearly stated it.
I felt so stupid, it was incredible.
In the end, the guy was very understanding and said that about 20% of the shops f'ed that up in Idaho. He knew I couldn't have bought the elk tag I had if I didn't have archery qualifications so he was lenient and simply warned me. He did say, however, that had I harvested an animal he would have had no choice but a full blown ticket and I would have lost my license for a year. No bueno.
Like you, lesson definitely learned!
