After setting up a builder the server is now crashing on startup, filter in the builder is setup as blacklist for cobblestone and stone.

    Minecraft Version: 1.11.2

I will check it out soon

This seems to be caused by another mod returning a wrong item for a block. Do you happen to know what the quarry was trying to break?

Thanks McJty, reported here ShetiPhian/Localizations-and-Issues#42

I do not, the game crashes instantly when I'm trying to find out. I can remove rftools mods and load the world but not sure at what point the builder is at. By chance could you build a version that outputs the location it is mining? I could find out what it was if I knew where it was mining.

yes, I can. Hold on

Can you try with this version:
http://jenkins.k-4u.nl/job/RFTools/lastSuccessfulBuild/artifact/build/libs/rftools-1.1x-5.84.jar

It has an extra print right before the line that is crashing

Thanks!

I think this is the line you are looking for?

[23:07:20] [Server thread/INFO]: [STDOUT]: block.getRegistryName() = terraqueous:foliage2

yes, so they have a buggy implementation then. You can report to them and tell them that their block.getItem() is returning null on 1.11 and that's an invalid result as null itemstacks are no longer allowed
