Possibly one of the lesser know features of Blueprints is that we allow the connection of an array of actors to the "self" pin of a function (see pic). This is essentially a shorthand for writing an explicit for loop. The underlying bytecode will correctly loop over each element and call the function using the current actor as the self pin for the node.
However, a licensee noticed that after dragging a connection from this array, the context menu did not list any of its functions as options. Considering that we allow this implicit conversion in the first place, it follows that the context menu should list the callable functions as well.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-155372 in the post.
