Did you change any startup settings and if so which ones?

I looked at the changes for the very recent version of 2.1 (released two days ago) and one of them is actually a fairly big one that would definitely break a few things, so actually I'm not too surprised. Thanks for the report.

Thanks for the great mod, my current run is on hold until this is fixed :)

The new upcoming update has changes that might cause things to be rerandomized. To fix this, I created this mod that does the bare minimum for compatibility: https://mods.factorio.com/mod/propertyrandomizer-fuel-category-fix

The catch is that I didn't test it. It loads with the randomizer and the new experimental release, but I don't know if things will rerandomize. Let me know asap if things rerandomize or you have other issues.

This works, thanks! I could continue my game without issues and rerandomization

i tried the 0.56.0 version with the new randomization logic but my seeds alwas lead to wood being used in things like science packs or something, which breaks automation ...

Was this with the preview checked or no mod settings changed? And were you on the default seed?

I checked with and without preview on the default seed and did not see this issue. Without preview (so old logic, not new logic) there is fish in a science pack recipe, but the fish is itself automatable, so not an issue. I'll need more details to be able to fix anything if there is actually a problem.
