Bloodstone The Ancient Curse

This is a recurring bug and keeps happening when I go afk. This time I was afk for a while, and when I came back I was logged out, when I log in and can't train.

This must be a bug, since getting punshed for being AFK, when you're allowed to be AFK would not be the case. I was thinking maybe I missed the captcha, but how can I hit the captcha if I am afk, it's impossible?

You must answer the captcha correctly whenever requested, it is mandatory for training.
