To many plugin but is seems nothing tested before released?
Assets/Addons/ScopePro/Scripts/bl_ScopeProWeapon.cs(24,19): error CS1061: Type `bl_Gun' does not contain a definition for `BlockAimFoV' and no extension method `BlockAimFoV' of type `bl_Gun' could be found. Are you missing an assembly reference?
Unless the unity version 2.0 1.4 13th of March is not the final.
Please if you can expedite the update.
