I am sure this is probably more of a mod interaction issue, but thought I would put it here so people will know about it. The rare shire with the block of ore that changes each time you break it; when you place an auto-breaker on it will create massive lag, so don't use this to automate breaking it. Also, I only learned about this shire when someone on the server showed me it. Is there something about it in the book that I missed? will there be more written about these shines? is there a way to locate them?

No it's intentionally not in the book.

And no, no way to track them.

Any usable information on this?
If not try hosting it on your local instance, replicate this and do a JVM CPU profiling on it and track the time it'll need for certain method calls. Then report back with that data, otherwise i can't help at all.
