Breakout in RND

[rnunziata]

I've run both pong and space-invaders for long training sets without any issues...but when I try breakout the system hangs some where inside breakout it never finishes the last life and goes into a loop. If a checkpoint is taken at that time then the checkpoint is bad and if restored the system hangs immediately. I do not know if this is a gym or torch issue .... has anyone reported something like this. I can replicate this easily.
