when I open the inventory, many of my slots appear to be empty, yet I can still use my weapons/armor etc. was wondering if there's a fix for whatever happened to cause this.

first thing I noticed missing were the default, infinite crossbow bolts, the slot was empty instead of having the unlimited crossbow bolts, then other items started going invisable in the inventory but not otherwise.

Already tried to varify game files, not sure if a re-install would help or not.
