Even if the question is for me, it's better for the community to have this
conversation in the searchable mailing list archives. So I hope you don't
mind if I add the list in CC.
In my recent posts I proposed making my simulation more reversible by

What makes you think that? In principle they should be... Are you using a
memory-optimized build? (typically reserved for huge systems, so not likely
for alchemical simulations)

Although alchemify should rarely be necessary now, I've moved it here to
keep it available:

Alchemify will modify the PSF for you.
