gmx solvate fails to overwrite topology file
running the following:
gmx solvate -cp /data/4KKE_newbox.gro -cs spc216.gro -o /data/4KKE_solv.gro -p /data/4KKE_topol.top
results in the desired topology file being output to a temp.top* file in the working directory, and the topology file specified by -p is not changed.
No error or warning is thrown.
If the generated temp file is used as input for grommps, it's got the expected number of particles.
