If I do the same with Al

That is, I take the Al structure and modify the ABC parameters slightly so that the system is now orthorhombic

it gives the same error, but with Na it does not give an error

I am doing calculations with Diamond slightly modified;
A=3.57, B=3.5701, C=3.5702 (Angstroms)
C:3/8, 3/8, 3/8
C:5/8, 5/8, 5/8
If I initialize in a terminal with
    init
It gives me the space group 70 Fddd
but later in symmetry it gives me an error;

********************

If I do it in the WIEN2k 'initialize calc.' using the 'fast mode' it gives me the same error.
If I use the 'individual mode' it does not give an error

I think that this is an error of the program, since the SG has been changed from 227 to 70, so it should have the reduced symmetry incorporated

I am using WIEN2k 17.1
