@SynapticSage I'm getting some errors and several hundred identical warning on the recent tests. sorry if its something I did, the last lines of the stack trace are:

I'll take a look --- it seems to be pettingzoo's parallel_api_test.

[TomGeorge1234]

Weird. Still breaking on GitHub but not for me locally. Yeah seems to be within the pettingzoo test. Wonder if its a bug and we can ignore the test or something we should worry about...

[TomGeorge1234]

Hm, update is that it seems to be stochastically breaking, for now I've commented out the test but we should dig into it.

[TomGeorge1234]

I'll leave it open for that reason

[SynapticSage]

Ya, noticing the stochasticity as well. I may not be handling an edge or corner case somewhere. I'll look at it when I catch some downtime.

The test in question uses an external call to is_terminated and is_truncated to manually track when an agent should/should not be "live" (i.e. active/un-terminated). I haven't seen anything in the agent videos ... but maybe the first or last frame of an episode.
