Crash Report UUID: 1615dca4-73a5-4b3b-b35f-e74367718b93

When I open the sleep on the traveler's backpack sleeping bag I lay down and the screen fades, but as the screen goes black and the switch to day should happen the game crashes. Here is the crash report info. I will open an issue on the BedBenefits mod page as well.

Well, that's not caused by traveler's backpack I think
Try reporting it to mod dev
