Issue with removing a mod from existing save

[nivnarna]

I started a survival server before realizing I wanted to remove a mod (Mr Pineapple's food mod)

I tested this on a copy and it seemed to remove fine, deleted all items and bushes from the world, left the generated structures but removed mod items from them. Then as I continued to play, it would crash with no explanation (exit code 0)

It won't save chunks, autosave and manual, saves inventory but no changes I make to the world, including chests.

I think it's due to a block called salt_rock from the removed mod, that forge for some reason hasn't removed and I need to find a way to manually remove all instances of it from my save game

No, no it does not. As evidenced by the crash log:

Quote

java.lang.IllegalArgumentException: Cannot set property BooleanProperty{name=east, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{pinesfoodmod:salt_rock}

Whatever the salt rock block is, from the Pines Food Mod, it does not have an EAST property, and something (apparently a vine block*) is trying to set it.

 

It may not be possible for you to fix this.

 

*My guess is that a vine thinks that a neighbor should also be vines, due to its own state, but its neighbor is not actually vines. This is an unfortunate unchecked situation in vanilla.
