C# code error after copy pasting

[Harambulus]

I had copy and pasted the global variable test.xml stuff form rostonix already but i had refined linking porceses in another template so i copy and pasted it over again and deleted the first one.

But now when i try and run it I get this c# error in log:

I cant get original code working now either since i deleted it and any new copy and paste gets above message.

Save and Restart project should help. Any idea how to reproduce it ?
