I'm currently a manager for a L4D2 Coop server and recently my players reported to me about the chapter repeating itself instead of moving on to the next chapter of the campaign. They also said that the S and SI bots sometimes don't spawn in when the chapter repeats itself. Even when they voted to change the map this bug continues to happen on the next map they moved on to. Whenever I restart the server it's fixed. But once everyone gets off the server and it enters into hibernating and wakes up again because a player joined, the bug pops up again. I'm not exactly sure what's causing the issue so I thought I can get some help here. Thanks for reading.
