The murderer can do /hat midgame to change their appearance
I submitted this as a bug report bc it doesn’t seem intended (/costume doesn’t work, neither does changing ur skin), but splodger said this was intentional game design so here we go.
When the murd does /hat and changes their hat midgame, have it do the /costume thing where it applies the change after the round ends. This would make the feature more consistant with other similar commands and actions, and the game more immersive/fair for everyone playing.
