Attempting to Change Global Variable to Local Variable in a Function Containing a Timer Causes Compiler Error

When attempting to replace a global float variable with a local float variable that is connected to a Timer node in a blueprint function, an error will appear after trying to compile.

This does not occur if you right-click on the variable and replace it that way, which is inconsistent behavior.

Found in 4.13.0 CL 3106830.

Reproduced in 4.12.5 CL 3039270.

1. Open the editor
2. Create two functions: Timer Function & Test Function
3. In Timer Function, add a Set Timer by Function Name node
4. For the Function Name, enter TestFunction
5. For the Time pin, promote it to a variable
6. Create a Local Float Variable
7. Drag the Local Variable on top of the global to change the global to the local variable
8. Compile

Result: Error appears:

Expected: The blueprint would compile without error.
