With the latest update of pyFusionEnergy, pyanodon introduced a bunch of tiered machines and so automated-screener
was replaced with automated-screener-mk01
and 3 more tiers. Because of that PyBlock started crashing with:
11.956 Loading mod PyBlock 0.0.12 (data-updates.lua)
12.095 Error Util.cpp:83: Failed to load mod "PyBlock": __PyBlock__/data-updates.lua:7: attempt to index field 'automated-screener' (a nil value)
stack traceback:
__PyBlock__/data-updates.lua:7: in main chunk
There might be more things that's broken due to new machines but this was the one that caused the game to crash.
