I just turned 50 and had been putting all my energy into that so I've also been ignoring the unspoiled nodes until now. I was trying my second of these which was in Coer West.

So I did Toil and SZ2 (because one was hidden). I swung once, got my yellow ore, went to swing again and the node disappeared.

Does anyone know why it disappeared? I didn't exit it nor was I interrupted. I didn't accidentally bring up my menu or anything of that nature. My chara was in the process of swinging the second time so it wasn't me.

Thanks so much! <333
