It seems that my down time is always 99 seconds even though I set "downTicks": 1000, in the config.

Have you tried fully dying before checking again? If a player already had data where the number was higher they will retain that until it's reset by say, a death

Mod version?
Game version?
Loader and loader version?

Have you rebooted the game or ran the config reload command built into the mod after making the change?
