Reproduction steps:
1. Create a new project
2. Import the attached “MobileControlRig.cs” file
3. Observe the script warning in the Console
4. Double-click on the warning to open the script editor and replace “FindObjectOfType” with the suggested method (e.g. “FindFirstObjectByType”)
5. Save changes and return to the Editor
6. Observe the Console

Actual result: 
{code:java}
Assets/MobileControlRig.cs(44,63): warning CS0618: 'Object.FindFirstObjectByType<T>()' is obsolete: 'FindFirstObjectByType has been deprecated because it relies on instance ID ordering. Use FindAnyObjectByType instead, which does not depend on ordering.' {code}
warning is thrown
Expected result: Initial warning suggests the correct replacement method and no other warnings are thrown after applying the change
