There is a known issue where if you leave the Editor unused for a significant time (it normally happens when the Editor tab is deactivated or your computer is in sleep mode), it can lose the connection to the server and silently fail to recover the connection. This means you can make changes in your scene but they won’t be reflected until you refresh the Editor. Examples are things like creating new folders/scripts/etc. It’s on our list. But yes, if you ever perform an operation in the Editor and something doesn’t happen as you would expect, a refresh normally fixes it.
