Questions about AdBF-QM/MM in cp2k

For the force-mixing labels, for me it works
I have 10.0 for list/core, 7.0 for extended and 5.0 for buffered. (for CP2K
version 3.0)
I have a parell question if I may:
How can we restart a ad-qmmm calculations ?:
I run a first dynamics, at the last step at the end i got:
QMMM FORCE MIXING final count (not including links): N_QM core_list 11
N_QM core 0 N_QM extended 42 N_QM buffered 111
And restarting it, the very first step :
QMMM FORCE MIXING final count (not including links): N_QM core_list 11
N_QM core 0 N_QM extended 33 N_QM buffered 87
+ the WFN: READ RESTART : WARNING : DIFFERENT natom, returning
131 164
So for the minimal QM region, I got only core_list, so it doesen't change
and it can read the WFN restart files
But for the extended, since it is buffer in buffer out related, it varies.
Is there a way to let CP2K now which atoms where in the extended/buffered ?
(Except putting the min/max the same for R_*** distances)
For info, these test were run on the 2.x (rev 16205) and i used:
R_CORE [angstrom] 0.0 0.0
R_QM [angstrom] 2.5 3.0
R_BUF [angstrom] 2.5 3.0
A part for the restart issues, which can be penalising when using
national/eu clusters where there is a wall time, it runs smoothly
Thanks
