Hi Bettina,
> Do you agree?
Yes!
Thanks for reporting.
I suspect a change done recently in order to make results *more reproducible*
[1], especially with multithreaded (-jN) runs.
But of course it introduces a difference between older and newer results (they
are all equally correct, though). It appeared in the master branch in June, so
if you could compare 7a4a71ef (after change) to 900c7616 (before) it could
confirm that.
If it doesn't:
- Could you paste here the exact script you are using, so everyone can
reproduce the "#add plate..." messages?
Suggestions:
- are timesteps the same?
- are all positions exactly the same at iteration 0, then 1? (you can just sum
all positions together and compare the result to make it simpler)
Cheers
Bruno

Unlike what the commit message suggests most of the reproducibility is
obtained even if loopOnSortedInteractions=False.
