Nullpointer exception when deleting blocks with effortless fabric

Sorry if this is the wrong place to report this, but I got a null pointer exception when deleting blocks with effortless fabric's floor tool around MI multiblocks/pipes. No pipes where in the selection, only adjacent to it. It does not crash the entire game, only kick me back to the multiplayer window (despite playing single player).

Effortless Fabric

[edit] This also happens when placing blocks with the same tool. I think this is the same stacktrace, but I included it just in case.
