Paper Scraps and Note pieces that are crumbled should absolutely work to make Molotov cocktails! I didnt realize I needed the papers so badly so now im regretting being so efficient with cleaning.
Nope, specifically only paper trash (the stuff you get from shoveling paper trash piles) works.
I doubt it is unintended either because every paper trash you can use in the molotov recipe is it's own individual recipe, it would probably be hard to miss every other paper item that could be used.
