Hi Dmitri, Try
editconf -f your_run_input_file.tpr -o test.gro to see if the box is stored correctly in the .tpr. Alternatively, you can do gmxdump -s your_run_input_file.tpr, and browse for the box in the output. Then, see if you can reproduce the problem with the last frame of the .trr file extracted, and consider submitting a bugzilla.
