Since it seems like new version gonna take a while I made a small reactions bug fix.
Fixes:
*unique metal bars now produces correctly.
*"remove netherwood bark" produce proper seeds. (i have no idea how to make netherwood itself usable as leather)
*"boil leather in oil" correctly leaves oil in container with 50% chance. - however I don't know how to make it not to use already boiled leather.
*"press oil from pig tails" now leave seeds.
If you're interested, you may grab it
here. By the way, if you have any ideas how to fix any of the existing bugs, I'd gladly include them
Regarding some other bugs to sum it up.
When you choose no nerfed traps game still leaves reactions for traps you can't actually use.
Steeloak bushes never gave me any plants/seeds, ironbark bushes likely nonexistent.
Butchering armored horses produce nothing.
Baking bread and sugar behaves weirdly: you can bake it only until bag with flour/sugar placed in a barrel. After that you have to get bag via dumping.
Wood prices for underground wood works correctly, but normal woodcutting produce wood with same value, be it scrap or fair.
Shells from turtles count as skin for tanning and produce common leather. Not sure if it's intended or bug.
Bonemeal counts as stone, but can't be blocked from stone stockpiles. On other hand it can be used for masonry.
Thats all I can remember for now.
