[tvwenger]

Interesting! I am not able to reproduce this error.

$ maxfield-plan example_portals.txt --num_agents 3 --num_cpus 0 --verbose --output_csv
Found 18 portals in portal file: example_portals.txt

Starting field generation with 8 CPUs.

Could you try installing maxfield in a virtual environment to see if it's maybe something funny going on with your packages?

python -m venv testenv
source testenv/bin/activate
cd /path/to/maxfield
python setup.py install

I tried downloading the mentioned font and extracting it into the build directory but it made no difference....
I have to confess that I have no experience with Python virtual environments.

BTW. I also tested on virtual machines running Ubuntu LTS and unstable which are using Python 3.8 and 3.9 - without any issues.
A freshly installed VM with Manjaro, which uses Python 3.10 also gave me the same error I have locally so I guess its the Python version...
Could you maybe test with 3.10?...

So... since I am not able to manage python virtual environments on my own... I used PyCharme to help me out:

The above exception was the direct cause of the following exception:

So yeah.. I think I can now confirm, that this issue happens when using Python 3.10 (and probably above..)
