Strange desync error in TrueSync's Farseer library

Context:

We added logging to let us know when 'rollbacks' happen. After a rollback, the physics broke - but it only broke in an external build, not the one that was running the editor. :(

Any ideas on what we should be tracking down?

    Hi @Xelnath, this is strange, can you reproduce in a sample project this issue? Because a lot of things can trigger an error on rollback procedure, it could be some mistake in our side or some in your game logic.

    Hi Jefferson,

    The scenario is complex. It's currently only happened once inside of the standalone binary and not happened again recently. The bigger issue is the inscrutability of the error. I will reply again here if it happens again and I am able to capture more debug data.

    Here's another one. Completely different character this time. The side-effect was the character acted like it was grounded (contact on the bottom circle of the character) - causing it to double jump in the air. Which is a side-effect of our code letting you queue a jump input before the ground collider amkes contact, so that it can respond right away.

    More. This time with 2 characters in the scene.

    Did you find something there? Rollbacks can happen more than one time per frame, it will depend on your rollback window settings.

    No, I still haven't. I just confirmed that the worst case scenarios were related to dynamically created bodies. I got stuck on the 'disconnect before start' problem and didn't get further into this bug.

    Did you try to disable rollbacks and check if the problem is happening anyways? Rollback adds some complexity, so it could be a bug there.

    At this point, I am unable to consistently play multiplayer together with two clients due to them desyncing almost immediately. Until that's fixed, I can't dig deeper into this issue.

    I set my Panic window to 1000 - and now the clients seem to have enough time to sync up about 60/40% of the time.

    Now I am getting this error which I've never seen before:
