Items being "downgraded" when logging back into Single Player PS5

[SirDavid]

I was playing Grounded PS5 Single Player and I managed to craft a few higher tier weapons, like the Mosquito Needle, Insect Axe, and such. When I saved and logged back in the following day, I loaded where I saved at, but all of my weapons were converted into Pebblet weapons (axe, spear, etc.) I have no idea how this happened, but I have lost my desire to continue playing until this is resolved.
