It seems some data wires’ connections are lost when restarting the editor. Only happens with data wires, not execution wires; however it makes it pretty unusable. In order to start playing my game, I have to reconnect about 20 or so lost connections across many classes whenever I restart the editor. Once those connections are reestablished everything works fine though.
This appears to be a problem experienced by quite a few others: Blueprint pin disconnects after restarting the editor - UE4 AnswerHub
I am posting this here because it might be something I’m doing–perhaps my classes are too complicated, or I am doing references wrong (it seems to be most common around getting data from references (i.e. Game->MyPlayerController))
By the way, I have had this happen in 4.12.5, 4.13.2, and 4.14.
Any help is greatly appreciated, thank you.
