This is a patch for the library Molten Plastic. This patches the error Failed to load mods: Error in assignID: recipe with name 'kr-electronic-components-molten-plastic' does not exist. This might work for 2.1 but 2.1 has a higher version of molten plastic so the error might be gone by then or mod owners have updated the definitions.

The patch is meant for 1.0.50 with game version of 2.0. It should unblock the rubbium lib not finding the molten-plastic.

This issue is mentioned in Molten Plastic discussion. I recommend removing this mod once the author fixes the issue or if things are unblocked in 2.1. https://mods.factorio.com/mod/molten_plastic/discussion/6a61c807db7b5a49083b2ae2.

There are no guarantees this patch actually allows the molten plastic to work. I have not been able to test this yet. Literally just made this to unblock a new game.
