if you can navigate to a combat map and die it should reset it. There's probably a few other things that will fix it as well, including a fade in item in the inventory if you can open your inventory and use it somehow.
Possibly sleeping in the bed could also fix it if the above methods fail(and the bed should be fairly easy to navigate to as its right next to the spawn point that morning!)
Im working on fixing this one as well as a few other major bugs for the next release as soon as I can make sure it's all working properly. There were a few issues like it including broken character storyline issues, issues with the new slime scenes, and more that slipped through the cracks, but once it's all fixed I'll do a bugfix update as soon as I can!
