Hiya RyokuHasu - Had a thing with chisel, it crashed the instance, twice. The log didn't say anything, it happened while shift-clicking a block in the world to chisel back along the list (2 shift-clicks on cobble, iron chisel). I suspect it internal to chisel itself rather than interactions in the pack, but a heads up anyhow, I'm looking into it
You might mention to people that the wooden bowl only picks up water from a still water block.
I'm having a great deal of fun... KnottedPuzzle
Update: It reliably crashes every single time when I do this, and I am attempting to force an error report. It would be helpful to know if anyone else can replicate this crash in a test world? This may aid in tracking it down.
