If I may hop in here, it would have been a bit kinder mechanics-wise if players would only have needed to confirm if their characters got a spirit guardian tattoo with no proof required. I'm mainly thinking of scenarios where people either didn't get to that point in their thread yet or simply couldn't find a partner to thread it out with.

I believe most players really care about this game's world, and being able to influence the outcome of events so greatly is exciting, so being unable to attain a bonus that could have turned the battle around (and a really cool reward!) for reasons out of one's control is a bit of a damper.
