Fixed a rare crash that occurred with the obelisk heart spawner

Fixed a crash caused by crystals being broken with a nearly destroyed tool.

Breaking obelisk blocks will now appropriately damage both pickaxes and chisels.

With passive/never hostile mode active, crystal locusts will no longer attack the player. In passive mode, Hearts will still get angry when attacked. Not in never aggressive.

Only one spawner exists per obelisk block now. This should prevent hearts from 'doubling up' on occassion.

Quartz crystal seeds can now be crafted.

Increased stack size of Crystal Hearts to 8.

Increased stack size of Crystal Grenades to 8.

Added better detailed death messages for heart/locust/grenade deaths.

Created a placeholder crystal planter that is the sole craftable planter. It better explains the crafting process for the variant blocks as a nondescript crystal planter.

Fixed an issue where crystal planters were not craftable.

Fixed an issue where obelisks could not be broken with chisels.

Fixed an issue where a patch to the arrow caused all vanilla game arrows to be removed from the creative inventory/handbook.

The Crystal Harvest

This update for Ore Crystals overhauls the harvesting mechanics for crystals and introduces a new means of growing your very own crystal farm.

It is HIGHLY recommended to also install my Item Lights mod. Many Ore Crystal items are now compatible with that.

Deep down in the depths of the world there are many temporal mysteries. A semi-sentient creature enthroned upon a structure of crystal is one such mysteries. It seems to burst with energy, enriching the local cluster of crystals with new life, causing them to rapidly grow an an unnatural rate. They even seem to have taken over the machinery of the depths, the locusts, infesting them with crystal and somehow influenced them to be their guardians.

It may be dangerous, but perhaps...these 'hearts' will be useful, in some way?

New/Changed Mechanics

Crystals can now only be harvested using a chisel or pickaxe. 

Crystals will grow whenever a Crystal Heart is nearby that infuses it with energy.

Larger crystal blocks can no longer be crafted. You can only grow them from seeds now!

New Creatures

Crystal Heart - A volatile floating orb of crystal that grows crystals in an area around it. Don't hurt it though...they tend to get quite moody, and the cave you're standing in will quickly become a minefield. Maybe it with you will calm it down?

Crystal Locust - Loyal guardians of the Hearts. These creatures will carelessly sacrifice themselves in an explosion of glass to keep you from approaching its Heart.

New Worldgen

Crystal Obelisk - An uncommon 2x2 structure found in the depths of the world. These will generate anywhere that an ore vein has a 2x2 space open to air above it. These are the thrones of the Hearts, and are a source of a new item, a luminous rod.

New Items

Crystal Arrows - A new type of arrow that is used to light up the area. Use it to illuminate a dark cave from a distance, or just use them to attack! They're sharp, dealing lots of damage, but have a high chance of breaking.

Crystal Grenade - A new weapon that uses the volatility of the Crystal Hearts. These will explode and deal significant area damage to anything nearby.

Luminous Rod - A rare resource gathered from large crystals and obelisks that are used for crafting.

Heart Core - The core of a Crystal Heart extracted with a knife. Used to create different variations of Hearts.

New Blocks

Crystal Seeds - A new, initial stage for crystal blocks. These are craftable by the player and will only grow with the energy from a nearby Crystal Heart.

Crystal Planter - A larger version of the potted crystal. Combine crystals with ore inside a planter to get a LOT of different, pretty glowing crystal planters to decorate with.
