Recently while running back to my grave, the game quickly shutdown with the error: Cannot encode empty ItemStack. After logging back in, my compass to my grave was missing, and the graves themselves were also gone.

Full error below:

How is this completed? I just got this same crash again with 'Cannot encode empty ItemStack'. Would be nice if you provided any info around an issue before closing it.

Logs and version?

Version is 1.21, I'm not sure how much more logs I could provide. The crash report doesn't give any more info, but here it is. Thank you for looking into this, I love the mod but am worried to continue using it given the chance that my grave could completely despawn.

You run outdated version of universal graves, latest is 3.4.1+1.21 and you run on 3.4.0+1.21

Ah so there was an update released on the day I posted this, could have been worth mentioning when you closed the issue. I'll make sure to update. Take care.

Yeah I closed it as new version got released
