Inaccurate natural object spawn chances

[connorhsm]

Currently, Rock and Seal show equal spawn chance rarity of the highest level, "Very Rare".

Their mapChance values are:

• Rock: 0.000015
• Seal: 0.05
• Ore vein: 0.005 (Comparison)

Each object has a mapChance value as well as optionally a list of biomes it can spawn in with the spawnChance of that biome.

• mapChance equates to the true probability of the object spawning and can be compared to any other object.
• spawnChance is the probability of the object spawning within that biome.

This rock is intended to be an outlier, but it's clear the grouping needs a tweak. This level of difference in the user experience equates to finding many seals nearby, but potentially not finding a rock after hours.

	spawnText() {
	if (!this.mapChanceData()) return;
	const level = Math.ceil(parseFloat(this.mapChanceData())*15)-1;
	if (level == 0) return "Very Rare";
	if (level < 3) return "Rare";
	if (level < 7) return "Uncommon";
	return "Common";
	}

It should be considered to review the current scale of probabilities and how we can expand the groupings to account for changes over time. We could also consider a fixed number of buckets which all objects are spread into roughly equally, similar to object crafting difficulty.
