after carefully enabling my mods one by one until i found the culprit, i have discovered that this mod and pacifist cause this mod (as "__propertyrandomizer__") to throw an error:
[C]: in function 'error'
__propertyrandomizer__/lib/graph/build-graph.lua:3793: in function 'add_dependents'
__propertyrandomizer__/data-final-fixes.lua:51: in main chunk
manually transcribed, as it does not seem possible to copy from in-game error messages.
i have updated factorio and both mods to no avail.
EDIT: didn't realise the forums use markdown; fixed
