pair/local granular

Dear all,

I have a problem damping the result of compute pair/local in granular simulations (13Apr17)

For instance, to output the distances between the interacting particles, I use following lines:

#### lines added 
compute c1 all pair/local dist
dump  dump_local all local 1 Distances.dat c_c1
dump_modify dump_local first no
run 1
undump dump_local
uncompute c1

I added these lines at the end of few example files, e.g. "in.min", and the result is as expected.

If, however, I add them at the end of the example file "in.pour", the dump file only contains the standard header lines, as if there were no interacting particles.

The same occurs if a try to output the result of a compute property/local.

Any suggestion?

Many thanks!
Massimo

​i cannot reproduce it with either the latest stable (11 Aug 2017) or the
latest patch ​(23 Oct 2017) version.
