now.. im not good with the large feature touchs... im not sure if this is the better way for handle the add again that CB patch.. or if is better fix that in the source file and the moonrise patch just need avoid deleting that...

The issue here is that we don't really want to be implementing this stuff into moonrise directly, as it will just be removed on the next moonrise update

then the fix its just modify the file and handle the merge conflict or exists a better way?

[electronicboy]

cept there will be no merge conflict due to how this stuff is applied, we need MR to add a hook or something so that the changes don't get wiped out on every update

[Doc94]

Ok i remake this... just copy the part of updateFluidHeightAndDoFluidPushing where get the last BlockPos for the fluid... and use that for update the BlockPos of lastLavaContact this require keep update that new method but avoid mess with the method touched by moonrise.

In general, I do not think this is the correct solution.

We will need to work with moonrise to add a hook into that method, which then through PaperHooks we could add the field setting there. I have notified them internally.
