Detail
In PR #619 we created a replay system to track down a bug caused in sumo. This has good utility for tracking down other bugs. It would be useful to re-evaluate these utilities.
The replay agent was partially integrated in #971
Context #619
It is not even certain that this is an issue any longer but it is necessary to confirm it to merge #1884.
