Emergency update

I was informed of an instance of a game-breaking bug regarding the Platy Entity that causes rapid multiplication of the entity. In trying to fix this, I also discovered that livebearer fish like the Auratus and Platy had a bug that caused fry to not grow up. That bug specifically is fixed, but I could not replicate the rapid multiplication bug and due to this the mod will be placed into Beta until the issue is fixed.

There was also an identifier mix up with Amur Carp terrestria spawns.

Goldfish and new body type system

Goldfish are another fish entity with procedurally generated variants, and it uses an experimental body type system that allows different body types for a single entity. The system is built on the same one that handles fixed variants like Ramshorn Snails and Archerfish. This is also another reason why the mod is going into Beta
