It seems that when the mod is used in signleplayer, it still expects the player to be revived so upon each death you need to click "Accept your Fate" (or wait). This is slightly different when you die in singleplayer with /kill, then there's no rescue screen but the camera is extremely shaky.

It'd be great if the mod disabled its features if it's not in a multiplayer environment - this would make it ideal for modpacks which are commonly played in survival.

Thank you!
