I'm not really supporting outdated versions of the game (considering the massive rework that had to be done for Factorio 2.0), but line 113 is part of the script that removes recyclers from a global list that is used as part of the automatic ingredient push (which pushes partial recipe ingredients to the output slots, like attempting to recycle 1 underground belt, when it was made in pairs). The list might have become corrupted in some way that some thing doesn't exist when it was expected.
Simplest fix (since I don't plan on updating for older versions of the game) would be to disable the automatic ingredient push, under the mod settings of an existing game. I think it's under per map settings. That will prevent these parts of the script from running.
