Exactly same problems here.. i cba attach any files.. couse some times works good others times works bad or at all like last few days so in my beginner opinion is some bot problem or server problem..
Important to mention that every time i have problems with GB2 like now or yesterday or two days ago, every time these problems happens Login attempts on the bot fail or are slower, also some times forum is more slow than usual + DB also DC exactly when GB2 have problems (prob same servers?)
