Dedicated server Replay file issue

[mdlp]

I have my 21b dedicated server exporting html results and replay files.

When accessing a b21 replay for the first time of a 20 rider grid there was no rider data present. No bikes visible and under the rider pull-down there were no entries.
Track conditions, race duration, smoke off the start line, dust particles etc were picked up.

I figured it was me but having tested this now with the M2 at Victoria, on two different dedicated servers I am of the conclusion this is a beta21b problem.

Has anyone else seen this or could possibly shed any light?

Cheers.
