You should be able to start a script with theStart(string) command if the script to load isn't loaded after the initial startup or the last full domain reload. However, you can't really reload scripts that's already loaded with the same paths but different content without entirely reloading the domain with theReload() command or a reload keybind. That's because we have to use the sameAppDomain inorder to keep existing script compatibilities for scripts built against v3 and v2 APIs.

I must ask this, how to reproduceliterally no effect by executing theStart(string) command? I'm asking it because I want to know how that command behaves. I can reproduce a entire process crash by calling that command with a file name that's already loaded after the initial startup or the last full domain reload (e.g. auto-loadabc.dll, callAbort("abc.dll"), 和 thenStart("abc.dll"). However, I don't consider things that crashes the entire process literally no effect, 和 I'll acculately say like "Start(string) crashes the game".

Yes, directly using Start(string) after automatically loading abd.dll crashes the game. When I used Start(abd.dll) without loading abd.dll, the script wouldn't load. For example: Start("abd") or Start(abd.dll) or Start("abd.dll"), which format should be used? I found through testing that the "" symbols must be added, the dll doesn't need to be entered, and using Start("PlayCutsceneV") is effective.
