RecursionError: maximum recursion depth exceeded when pickling

[EwoutH]

I would like to save the World object to analyze later, but when saving with either:

model1.uw.save("model1_uw.pickle")

or

import sys
sys.setrecursionlimit(1000000)  # Example: Set the limit to 1500, adjust as needed
with open("model_instance.pickle", "wb") as f:
    pickle.dump(model1.uw, f, protocol=pickle.HIGHEST_PROTOCOL)

It throws a RecursionError: maximum recursion depth exceeded message.

Reproduce

I don't have a minimal reproducible example yet, buy it can be observed by running model.py in this repo and adding model1.uw.save("model1_uw.pickle") at the bottom. The error can also be observed in this CI run.
