Pretty log and raw log don't match

[YorikSar]

Describe the bug
It seems when a build is retriggered, "pretty" log keeps showing the old log, while "raw" log shows the new one.

To Reproduce
Not a reproduction, but an example:
Build: https://hydra.nixos.org/build/319408938
First attempt pretty logs: https://hydra.nixos.org/build/319408938/nixlog/1 - the same as the second attempt pretty logs: https://hydra.nixos.org/build/319408938/nixlog/2
Raw logs both show the second attempt: https://hydra.nixos.org/build/319408938/nixlog/1/raw and https://hydra.nixos.org/build/319408938/nixlog/2/raw

Expected behavior
Both logs for each attempt should match and show logs relevant to that attempt.

Hydra Server:

It's https://hydra.nixos.org, with this footer at the time of the issue:

Hydra 0.1.20260105.41daeb3 (using nix-2.32.6 and nix-eval-jobs-2.32.1).

Additional context

@K900 did the retriggering of the job, might have more information.
