I have a feeling that the reason DBNO device doesn’t work, because there are settings in «Island Settings» device in “Eliminations” tab that override DBNO device entirely.
I inverted teams in DBNO device, I disabled DBNO in «Island Settings» device, I tried everything, but DBNO device custom settings do not work.
You can still control DBNO device through Verse (you can use Down() function), but settings like: “Custom tenacity”, “Time to revive”, “Last Man Standing Mode”, etc. — do not work.
