the median score from evaluation server seems to be much lower than local test

@eric_hammy I trained torchbeast_agent from scratch for 1B, and tested the model using test_submission.py. I did 5 test runs, where each run evaluated 512 episodes, and the resulting median score was 400 +- 25. Then I submitted exactly the same model and code to the evaluation server, but the computed median score was only 322, which is much lower than my local test result (400 +- 25). What could make the difference between local and remote test results? The submission ID is 149676, and config.yaml is as below.
