Unreal Engine didn't search in closed blueprints

Hi guys,

I have discovered the problem, that the Unreal Engine, from time to time didn’t search references when the blueprint that is using reference is not opened. But when I’m opening the blueprint that is using the reference, function, or event, the search is working again.
Maybe there is a way to load all blueprints on startup because it is very important to be sure that search is working at all code.
And usually, it is not working only for Widget blueprints.
