Error with Locpot.from_file/Species.from_str

[VicTrqt]

Problem When I try to instantiate a pymatgen.io.vasp.outputs.Locpot object from the file, I get an IndexError from the Species.from_str call. I am using pymatgen v2023.11.12. Example

Update I noticed I had the same issue when trying to instantiate a Structure from a CONTCAR file... It seems that my compilation of VASP produces a CONTCAR file that features a slash after each element on the 6th line such as X/ Y/ Z/ instead of the usual X Y Z. It works as it should when I remove these slashes.

I think it would be nice to be able to treat this situation directly in pymatgen.
