This has been a problem for us on our private server as well. We have no mods, and did a fresh wipe for this patch.
I notice that the logs are being spammed with this every few seconds. These messages do pop up in logs from time to time when players lag, but it’s the first time I’m seeing Control (Server) in a message like this… and the values are very large compared to the threshold. Normally when lag used to happen, any such messages would only be a little higher than the threshold.
I believe this to be an indicator of the lag. Maybe others with private servers can confirm they have similar messages in their logs?
