That seems excessively long, even for a busy night. How often does this happen to you, and is it only tied to certain times? Can you try it during non-peak hours and see if you get the same results? Does this universally affect all players, or only some of them? You might want to try the debugging steps and see if this makes a difference: Can you please follow Steps 1-3 of our Solving Technical Issues wiki page, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including providing all of the necessary information, so that we can further assist you. You might try making a duplicate of that campaign and see if it happens in the copy? If it does, try clearing the chat log and see if that makes a difference.
