Sure thing! I was actually thinking about it, do you want me to open a PR in SuperSuit and refactor BaseParallelWrapper there as well?

[jjshoots]

@mikcnt that would be ideal, yes. :)

[mikcnt]

@WillDudley @jjshoots I've opened a PR on SuperSuit as well (Farama-Foundation/SuperSuit#204). Let me know if that's enough!

[jjshoots]

Honestly, the fix is so straightforward and I just want to get this overwith. Already merged the one on SS so hopefully this one passes, otherwise I'll hot fix it.

Sorry, didn't see the message before. Thanks!
