What type of bug are you reporting?
Mechanics
What is the bug?
Falinks(and other ghost types) can spam no retreat when ghost(either through tera or base type). This only works with ghost type, not other forms of trapping prevention. This differs from in-game implementation, where it still applies the "cannot switch" effect that prevents no retreat from working, even if it doesn't prevent switching(backed up by bulbapedia and in-game testing)
