So I’m using the become command for one character to change into another: @KORA becomes MIRROR an it’s working fine, but then when I try to change it @MIRROR becomes KORA it isn’t showing. Is it just because I’m previewing it on the writer’s portal, or am I doing something wrong?

The becomes, changes into, and previews commands have 0 beats, so yeah you would have to add a pause right after she changes
