error with Function xx is currently not available

[pbl357]

Hi, thank you for great reaver,
I test the run.py with --env MoveToBeacon --agent ppo --n_envs 1 in macOS without GPU, but get follow error

Traceback (most recent call last):

the error about action id is not same every time.
then I run the command python3 -m pysc2.bin.agent --map MoveToBeacon, the result:

my pysc2 version is 3.0.0 , reaver version is 2.1.9
I had set the ensure_available_actions=False and it works,but I dont think it`s good idea
