Hello @BadLandPVE
This is quite odd, as I tried to reproduce it on my development server without any luck.
My only suggestion as of now is to enable DebugType.All
Open up the AdminToggle.cs file and find the line
private const DebugType DEBUG = DebugType.Disabled;
And replace with
private const DebugType DEBUG = DebugType.All;
Once debug mode is enabled, try to reproduce the error once more and a log file should appear in Oxide/Logs for AdminToggle, with all events leading up to the issue.
Please share this file with me thanks
