Hi @karl. Thanks for pointing this out. Last week we released v1.3 of the binary and gym interface which fixed a couple of issues participants were having. We didn’t yet update the challenge repo to target this latest version.

I just pushed a fix to master branch of obstacle-tower-challenge which should address it.
