Been babysitting for like an hour @ 3 different locations/ on different agility level accounts and my only problems were:
Gets stuck if the "Cross Hand Holds" @ Falador is failed. So far any other agility fail i've seen @ fally is fine
Got stuck once failing the far north tight rope, ended up freezing all of osbot for me -but not the client, i could still see the paints timer ticking/npcs moving.
Failed this again, same thing happened osbot froze but rsclient was fine, fixed itself after about 3-4 minutes. but i had already spam clicked to turn the bot off so not sure if it wasn't fixing itself or not.
Hasn't picked up any marks ///EDIT: Picked up one mark it happened to run directly over
