The fix that is coming doesn't address this issue. (The fix is just a
convenience: if you don't know how many ions you need to neutralize a system,
tleap will now do a better job of estimating that.)
We may be able to force antechamber to come up with charges that sum exactly
to zero when each charge is truncated to three digits. But it's a little
tricky to actually do that, so don't hold your breath.

I have not seen this in my own work. It would be interesting to see pointers
to particular examples.
