run_baseline_parallel.py does not seem to restart from checkpoint? about pokemonredexperiments HOT 4 OPEN

Ah, this was left over from some old experiments. If the folder isn't found it will start a new training session. If you point it to an existing one, it will restarting training from that checkpoint. This could definitely be made clearer in the code 🤔

I was able to get it to restore the latest session but I'm getting an error. Maybe someone sees what I'm doing wrong. I added the code needed at the bottom.

I just noticed you can read "saves_to_record.txt" and get the last value instead.
