I have already moved the files one by one and the result is that I cannot be on duty with the callout files.
But I noticed that since the beginning of the problem, there was a message from Damage Tracker Framework saying, "Cannot detect version due to server down or your internet connection issue."
Then, I turned on the VPN, and the game worked just fine with my original plugins folder. I think the problems have been fixed. But may I know if the internet connection issue is affecting the Force Duty command or On Duty at the PD station?
