Hi,
Firstly this looks like a great plugin.
Hope you can help. I have just added this to my 7Days to Die server and keep getting the error BetterChat.cs(436,46): error CS0012: The type `System.Xml.XmlNodeList' is defined in an assembly that is not referenced. I have seen someone else have an error with another plugin of yours like this and it was becuase 7Daystodie does not include system.xml DLLs

Please make sure you have System.Xml.dll and System.Xml.Linq.dll under your server install location, 7DaysToDieServer_Data\Managed. The issue is not with this plugin.

I really appreciate you getting back so quick. I have checked that and the files are there. I have even tried redownloading the files and uploading again with Filezilla. I have even gone to the extent of wiping everything and setting up 7 Days again as a fresh server and trying again and still the same issue. 
One thing though is that my host I have my dedicated server with has an aoption to install Oxide via Umod as it will not install otherwise. Maybe the version is out of date?
Filezilla Showing Files

What does the oxide.version command show?

Ahhh yeh using that command shows 2.0.3852 and the latest version on the website is v2.0.3855 maybe thats the cause. I'm onto my server host now and am trying to get them to update the link. Really appreciate you getting back to me. Great support :)

I'm not sure that will resolve the issue, currently testing with it locally to apply a fix to the core.

Thankyou. Thats great to hear :)

The latest Oxide.SevenDaysToDie build fixes this.

Amazing! I'm just waiting for my host to uplaod at their end and will post here to let you know how I get on :)

Merged post

Its working now! I can't thank you enough!
