Minecraft Version: 1.12.2

Not really a bug report.

The infinite blocks that lose all stored items/fluids/energy when broken should take a while to break. Currently even with a stone pickaxe they break very quickly and can accidentally be broken.

What would be even better would be a tool to toggle an indestructible state to prevent any accidental breakages.

Not saying they shouldn't be harder to break (maybe be at least as hard to break as the default ingredients), but as a reminder the mod comes with a tool that insta-breaks everything. The exception being blocks specifically protected/unbreakable. So if you are playing a pack that has something like RFTools' block protector, you can use it to prevent your vital machines from accidentally being broken.

I am not the developer for this mod, I am simply offering my thoughts.

Closing as basically a duplicate of #32 and opposite request of #20 See my comments there if you want more game play explanations.
