Steps to Reproduce

How often this happens: Enough for it to happen at least once in an enclosed space after a few hours of gameplay
Step 1: Build house out of player made materials such as skyroot planks and holystone bricks, no naturally generated blocks
Step 2: place ambrosium torches inside player made structure until it's acceptably lit

What You Expect To Happen

Player made house should be spawnproof, no mobs, hostile or passive, appear without warning in the player made structure

What Actually Happened

Aerwhale appears inside of player made structure and gets stuck inside

Additional Details

Outside of this example, giving the player more options to control where and when mobs spawn in the aether would only improve the experience and make it even more fun in my opinion.

Related to spawnproofing: I'm thinking more and more it might be good to allow spawnproofing methods for other hostiles like swets and aechor plants, but they may depend on how we adjust their spawning.
