Lost Atoms When I Changed the LAMMPS Version.

Hi, Everyone.
I meet a problem that I can run the code well on LAMMPS ( 13 Sep 2013),but I got an error that Lost atoms when I tried to run it on LAMMPS(14 May 2016). I am very confused about this . So if there anyone could solve this problem for me ? Thank you very much !

​you are the only person that can solve your problem.

LAMMPS is continuously updated and improved. bugs are fixed and sometimes
new bugs introduced.
sometimes defaults change or semantics of commands change. sometimes things
work without crashing, even though they are bad and then fail, when bugs
are corrected. sometimes you have a marginal input that just works by
chance and then fails when something minor changes.

at any rate, you have to trace down the cause for the lost atoms as if it
would happen with the old version as well.
