Yeah its Hotload most likely, it’s kinda flaky. I by habit do 2x compiles in a row just because hot reload fails about 50% (with no errors). And every once in a while, the entire process can become stuck, and you must restart the editor. (one time I couldnt disable the cursor from showing, no matter what I did, tried for like 2 hours with code and blueprints and what not) restarted editor, code starting working cursor was disabled finally.
People say live programming is better, but for some reason I cannot enable mine, go figure, I might have to start a new project and migrate everything if I want to use the live coding feature.
