I have both your plug-in Server Armour and Ember ban management (another plug-in listed here on uMod) plugins installed on my server but when I have both installed I noticed that SA does not pull player data from SA servers and metadata sources and save it anymore in the data folder. The data it records in the SA player folder in the Oxide data folder is all null values. I noticed that Ember has replaced the /ban and /unban command from SA and when I try to reload the SA plug-in with Ember installed it gives me the following error:

I would like to use both of these server ban management plug-ins concurrently and hope they can work together as I'd like to receive player data from players on the server from SA and submit ban data to SA while also maintaining Ember ban management for local administration as well :)
