Yes, you got it right
. i did that on older versions, but on this it's not working. First i got errors because i had old sourcemod version, but now i have 1.8 and getting that 035 error. When i try to compile sourcebans.sp without any changes i had same error. Maybe i need some inc files or different sourcemod verssion?
Now i dont have that error, but im not sure if it works. Just removed AuthId_Steam2, i just think that i dont need that
