Dear Pietro,

No, I don't think so. There has been NO update for pytraj for at least the
last 6 months from the release.
How did you install pytraj (via ambertools?)
Can you turn on the pytraj's verbose to see the message from cpptraj (which
is used by pytraj under the hood):
pytraj._verbose()
pytraj.write_traj(...)
What's your exact commands?
Can you reproduce the issue If you replace your systems with the tests
system (tz2.ortho.nc, tz2.ortho.parm7) in here:
