This mod can cause desync in multiplayer. Please use the global table (see https://lua-api.factorio.com/latest/Global.html ) for storing data surviving between multiple ticks so it's save-load safe.
I know this was intended mainly for Mukkie's SP playthrough but someone can download this and get a desync in MP.
Thanks for the heads up, I thought it wouldn't be an issue since the table is filled and cleared in the same tick. This whole idea was a long shot anyways and it doesn't seem to help, so I'm marking it as deprecated.
