Can't cast to custom blueprints in 4.5?

Myself and know how to cast to nodes as we have done in 4.4 but when moving our project to 4.5, something broke and now when we attempt to cast an actor to another type of actor, the node to do so can’t be selected off of the menu where it appeared in 4.4, context sensitive or not. I am still on 4.4 and one programmer moved to 4.5 to experiment with UMG. I have to send him blueprints with casting to character and playercontroller blueprints so he can copy and paste them into his blueprints, because they never show up to be generated. When dragging off of the return value of a cast to custom blueprint, he can’t even get or set variables without turning off context sensitive which is clearly not intended to my knowledge. I think it’s specifically an issue with projects converted from 4.4 to 4.5 because this works as intended using my launcher version of 4.5 with blueprints generated within 4.5. I think there is some kind of issue with blueprints not being aware of each other, but don’t know much beyond that. The casting nodes which are copied DO work, but those nodes can’t be picked off a menu anymore in our projects.
