Unreal Engine Issues and Bug Tracker (UE-44303)

Description

I had a tester with VS 2015 run through the steps I failed with, and they were unable to repro. JamesF was able to repro the issue on VS 2017.

JamesF pointed out that this does not occur is you choose to rebuild your project instead of building it when you encounter [Link Removed].

Steps to Reproduce

Setup:

Create a Code project using the first person template.

Repro:

In the editor, click the Compile button on the tool bar
In Visual Studio, open the MyProjectCharacter.cpp file under Source > MyProject

Find the line

FirstPersonCameraComponent->RelativeLocation = FVector(-39.50f, 1.75f, 64.f);

and change the 64.f to -64.f

In th editor, PIE and click the compile button on the tool bar
Close the editor whn [Link Removed] occurs, and click build your project in Visual Studio
After the build completes, reopen the project in the editor.
In Visual Studio, open Source > MyProject > MyProjectProjectile.cpp
Find
```
OtherComp->AddImpulseAtLocation(GetVelocity()
```
and change the float value from 100.0f to 1000.0f. Save the file.
Switch back to the editor and click the Compile button

Result:
Compiling fails with Linker errors.
