This is the latest crash file from the issue

As I understand it, connecting a fluid pipe to an item pipe will cause the game to crash on worldload.

Workaround is to completely delete the mod, but upon adding the mod back, the game will crash again. I've tried deleting "refinedpipes_networks_minecraft_overworld.dat" but then I get another error saying that the network is "null"

LMK if there's any other info you need
