Change variable drag with empty reroute node makes engine stuck

Hello,

Today i encountered a bug in Unreal Engine when changing the variable by dragging over with a new variable when the to-be-replaced variable has a empty reroute node and a node(Get Forward Vector and Get World Location confirmed, however i’m sure others will have it too).

The difference i see is i get “warning this will break links” when trying to do the change, however it does tell me the same warning when only having a reroute node and it doesn’t get stuck.

I can confirm this is happening in 2 updated projects from 4.10 and in a clean newly created project.
This is also happening in a 4.11.1 source download from GitHub.

Version:
4.11.2-2946394+++UE4+Release-4.11

Download from Launcher.

Reproduce the steps:
Clean third person BP
Get follow camera
Get Camera boon
Get Follow camera - > Forward vector
Get Follow camera → Reroute node
Try to change Follow Camera into Cameraboon by dragging over it with the variable from the components tab.
