Just a little more info, when i start debugging from Visual i get a few errors:
Ensure condition failed: ToPin->LinkedTo.Contains(this) [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.8\Engine\Source\Runtime\Engine\Private\EdGraph\EdGraphPin.cpp] [Line: 148]
UEdGraphPin::BreakLinkTo Pin '' on node 'None' not reciprocally linked with pin 'ReturnValue' on node 'Outputs'
UE4Editor.exe has triggered a breakpoint.
There are 3 failures all with the weak description on node ‘None’. I hope this can help judge what is wrong right now.
Thanks
