Hello!
Every time I let the bot run for more than about 5 hours, it get's a "global critical error", which doesn't sound very good.
The error seems to occur when the CAPTCHA engine is running, but I'm not quite sure. My reason for suspecting this is that every time I log on after the error has occured, the account is stuck on the bot protection page.
This could also be because after the bot crashes, it keeps logging in and out a few times every minute. I haven't been online at the exact moment when the error occurs, which means it could either be that the error occurs when the CAPTCHA engine is running, or it could simply be random, and that the bot protection shows up after a few minutes / hours of the bot logging in and out all the time.
The fact that the bot stops working after about 5 hours doesn't bother me too much, but the fact that it keeps logging me in and out until I physically turn the bot off is a bit worse. That's the kind of thing that will get me banned.
PS: This whole problem might be related to the fact that after the new browser system, the bot pretty much pushes my computer to the limit. The bot + all the other applications the bot runs uses up 100% of my CPU. After a couple of hours it could simply be that the bot is "overheated" or something.
