Every time I try to automate the rock grinder machine, I get the grinder item stuck in the stone slot if I run out of stone...

Added :)

Well... I think you broke it...
Now smooth stone goes in to the output and gets stuck there...

Well...development on 1.11 has been stopped. sorry :(

So, basically, you're abandoning an incomplete\buggy product that many people use in their pack...

I believe I can fix it myself, if you'll give me your permission to work on it.

I'm moving on from 1.11. Yes, I know it's an issue that (some) people have to deal with. There's other ways to do it in 1.11 (mechanical user, etc). Sorry again, but some issues have solutions to avoid it. I'm not going to go through the trouble of reverting my work environment, and I don't want others to be building the mods at this time

Well... I do hope you'll reconsider at some point, for now I'll revert my pack to an older version of your mod until I'll find another mod who'll be capable of the same things...

Sorry for inconveniencing you, and thanks for all the hard work so far...
