I searched around and couldn't find any similar issues.

A map with replays enabled from start and no mod changes (only using LTN) desyncs when trying to load the replay. The save was created in single player (with the mod enabled), then transferred to a server (with the mod enabled). The map was then run by the server in headless mode (on Windows).

Is there any chance to skip the CRC check and just let the map play out even if the results are wonky? I'm trying to generate a timelapse of my save from the winter holiday.

Otherwise, is there any chance of enabling replays going forward?

Save file attached.

I've given this a few attempts with no success, and have looked into some of the mod code.
I don't see any issues - why is it desyncing on tick 60 and not tick 0?

Also made a 60 second replay with the same mods and no issue.

I had a hunch that your mod settings are different from those that were in the save, but i tested this and couldn't create any desyncs (it was stopping me from changing settings)
I'm not sure how you would go about fixing that if this were the case, there doesn't appear to be a sync settings button.

And because the save is only 8 hours old, i doubt mod updates are a factor.

This may also be related, given that replaying a save in linux has in the past given a desync where in windows (i presume) it would not.

Thanks for testing out the save on your end, and the same mod setup. I wonder if I had generated the save file using the headless server if it would have worked.

Is there any way to disable the CRC check, or to repair the replay file etc?

This is most likely an issue with the mod, and we won't act on the report until the issue can be reproduced without any mods present
