Can reproduce. Happened when copying settings from a Bob's/Angel's Chemical Plant to a Constant Combinator.

Does anyone have a save file they can share where this can be reproduced?

The code for this mod does not have an "on_save" method, so this must be coming from the game engine trying to save the game state of this mods global table.

I can reproduce this error anytime I try and copy a recipe that includes fluid.

Try with my version of this mod .. https://mods.factorio.com/mod/AdditionalPasteSettings ..

I pasted a blue belt recipe (which has lube) into a requester chest and combinator then save the game .. no crash.
