Hey, not sure if this has been posted already but I encountered a bug that completely freezes the engine. I’ve tried it in a few engine versions. This **Does Not** crash in 4.11.2 or 4.12.5 but it **Does** crash in engines 4.13.2, 4.14.1 and 4.14.2.

**First I added 2 reroute nodes in Blueprint:**

**Then when you move any of the Reroute Nodes so far, the connection line changes from the “S” line to a “)” line**

**Finally if you try to reconnect the Reroute Nodes back to each other (Dragging from A to B in picture below) the engine freezes on this screen.**

**Doing this on Engine Versions 4.11.2 or 4.12.5 results in the Reroute Nodes being reconnected in a loop (Picture below) whereas 4.13.2, 4.14.1 and 4.14.2 crash**
