Is chutney generating only some relays?
Looking at the pipelines jobs, i see that sometimes is not generating or detecting all the relays. For example, in: https://gitlab.torproject.org/juga/sbws/-/jobs/13954#L6181 and https://gitlab.torproject.org/juga/sbws/-/jobs/13947#L6462, relay_prioritizer
is only seeing some.
However it hasn't happened to me locally. Maybe some timeout or lack of memory in the Gitlab runner.
