Is it not possible to duplicate safety-gymnasium environments? Is there any other way to save and restore the exact state after calling step?
My use-case requires me to implement a sort of "undo"-functionality and I was trying to simply save snapshots.

Questions
Hi,
thank you very much for providing safety-gymnasium and supporting us in using it.
I tried to copy an environment with deepcopy:
However, I receive the error trace (originating from the deepcopy-line above):
