[Wien] Error during abc & gamma (4D) optimization of a monoclinic system

I took your attached Nb2Se3_all_min_initial.struct at [1], kept the 
structure the same but swapped the lattice angles (beta<->gamma), 
lattice constants (b<->c), and atomic positions (y<->z) in StructGen of 
w2web and generated the new symmetry operations for it with "x symmetry" 
which gave the attached Nb2Se3_all_min.struct following the advice at:

https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg12124.html 
<https://urldefense.com/v3/__https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg12124.html__;!!Dq0X2DkFhyF93HkjWTBQKhk!FEEtwhA5ust8qZ33lpDr8XYIkrrX9Q-5dJZwtsegrpZeCBDX0vBodglHQ7hv6bvcYwvi9Q$>

I then ran the 4D "x optimize" on it using WIEN2k 19.2 as given below.  
I'm not able to reproduce what you have described as instead it looks 
like the "x optimize" script changes the gamma angle just fine from the 
original 104.153240 degrees to other angles such as 102.070175 and 
106.236305 in some of the .struct files.
