Hello there.
I’m having an odd problem, whenever I add another blueprint interface to a blueprint actor I get the following problem: The nodes disappear and the node lines start flashing, I can’t edit any of the code. When I try and run the game in editor it tells me the blueprint has compiler errors…
This happens no matter what order I add the blueprint interfaces.
Has anyone ever come across this issue? Is it a bug?
Do you have a circular dependency loop in any of the BP interfaces?
It seems to be going into a feedback loop once both are added.
Try creating a fresh empty interface and see if it’s the number of interfaces or the specific combination of these two.
Which version of the engine are you on?
I’ve got 5.0.3 (I’m just installing 5.1 to try)
I can’t see any circular loops?
Created a fresh interface with the same interface as BPI_Shootable, it did not appear to show any errors 
Thanks @3dRaven
It must have been something to do with me “duplicating” the BPI_Interact to create the BPI_Shootable. Created a BPI_Shootable from scratch works
