Describe the bug
The $ffnb section doesn't make sense during GFN-FF optimization. I followed the guide in the Manual neighbor list setup, but the atom 2 and 8 still exist in neighbor list of atom 1.
To Reproduce
Running with xTB-6.7.1.
The input files La-Complex.xyz and xcontrol are copied from the document.
