Haven't gotten 5x5 pattern but guessing it's probably the same.

When breaking blocks with limestone within the 3x3 box, Limestone will not break. This even occurs when Limestone is the block you're breaking and there's adjacent limestone blocks; It'll simply break the targeted limestone plus any other non-limestone blocks.

Also affects marble. I'll update if I find more blocks.

AA ver?

r129

So far those are the only two I can find acting differently, only did a little bit of mining though so can't say for sure if those are the only two.

I feel like the nearby hardness comparison is missing an equals... Bleh. I should have time to work on it soon

Obsidian is also affected.

Yes, it also does this using 5x5 augment, with a range of different blocks/ores it skips (doesn't mine)

Working as intended in new update. Thanks!
