When both Spice of Life: Carrot Edition and Backpacked are present the Player can't respawn after dying.
Respawn button does nothing. The only way to respawn is to disable one or the other.

Demo:

Thanks for the report. This was an issue in my mod.

Glad you found the issue! (and before I even got around to checking that email lol)

I went ahead and closed it on our end too :)
