Removing an idol from a room won't disable the auto practice setting in this room. However, the idol that you removed won't get picked up for any auto practice for 1 minute.
Bugs
Fixed: Idol salary getting stuck at ¥1,000 when using +/- buttons
Fixed: Popup for manually changing idol salary not displaying any text in Japanese and Chinese versions
Fixed: Idols that work in a cafe could show up in multiple rooms at the same time
Mods
You can now create custom auditions. Use this dialogue effect (available in the latest version of the editor):
Meta -> Custom Audition -> IDs of unique idols separated with spaces (at least one idol, up to five)
You can check how it works in the updated Unique Idol Example Mod
