Can someone with enough knowledge of the internals chime in on this?

Can someone with enough knowledge of the internals chime in on this?

That looks like a sensible explanation, but the only one who can answer that question is Johan, since he is the only one with both source code access and the requisite understanding of programming issues.

I sent Johan an email about this. All we can do now is wait to hear back from him.

If I followed that link correctly, that isn't the issue. Or at least not the only issue.

The question there is about different results on different architectures or optimization settings. The current version of the replay bug can occur even in SP games where the actual results and the replay are run on the same machine.

Hi Edi, I'm pretty sure that isn't the problem with dom3. But intereting problem anyway.

So that's the official word for now.
