I’ve recently started to experience freezing while working in the Blueprint editor. I don’t think this ever happened with 4.16 or below, but I’m not completely sure. Once the editor freezes, no memory gets allocated or deallocated until I kill it, and the CPU drops to <=1% but doesn’t seem to stop completely.
I’m curious as to whether I’m the only one who’s experienced this, since my project is very heavy and I’m using the Blueprint search functionality very frequently. So far it has only happened when I have the Blueprint editor maximized and in focus, but I suspect that it’s just coincidence. Other than that, there doesn’t seem to be a pattern.
