Game freezing / general robustness to wrapped game engine

I've noticed that when randomly sampling actions in real text games (e.g. ZMachine games not generated by TextWorld), the game inevitably freezes/segfaults at some point (It seems like Jericho has the same issue). Since TextWorld is a RL environment for text games, can we make it more robust to these problems? For example, having a timeout failure or game crashed failure?

Here's a code snippet that consistently freezes on my machine:

# !mkdir -p games
# !wget -q http://www.ifarchive.org/if-archive/games/zcode/Balances.z5 -O games/Balances.z5

import textworld
import itertools
import tqdm
import numpy as np

np.random.seed(0)
episodes = 50
episode_len = 500

scores = []

for episode in range(episodes):
    print('episode {}'.format(episode))
    env = textworld.start('./games/Balances.z5')
    env.reset()
    env.seed(0)
        
    verbs = [w.word for w in env._jericho.get_dictionary() if w.is_verb]
    nouns = [w.word for w in env._jericho.get_dictionary() if w.is_noun]
    actions = [' '.join(tup) for tup in list(itertools.product(verbs, nouns))]
    
    for step in tqdm.trange(episode_len):
        act = np.random.choice(actions)
        print(step, act)
        game_state, score, done = env.step(act)
        if done:
            break
    scores.append(score)
    
print(scores)

Run the supplied Balances.z5 reproduction first, then inspect textworld.start(...), env.reset(), and env.step() around the wrapped Jericho engine. Done should be demonstrated by the environment reporting a timeout or game-crashed outcome instead of freezing or segfaulting.
