Hey all, and hopefully mod author,

Am currently making creeper & zombie spawnable by adding a spawn.txt file to the mod folder.

That much works just fine. However, the creeper floats around in the air where you place it, instead of walking on the ground, and returns to floating even after being knocked over.

The zombie also floats, but just dies as soon as it tries to move. Also, the zombie's legs sometimes clip through the floor, causing it to die.

Placing the assets in the mod editor seems to work just fine, and I can even fill the zombie and creeper rooms with as many as I want. It's just the spawning behavior that's broken.

I have some experience with Lua scripting, so I looked through the script files to see if there was anything that causes this behavior, contrary to the robots. It could be my lack of experience with teardown modding, but I have no idea what could cause this!

Just for fun I made a nearly indestructible zombie by reducing the "remaining voxels" count that determines when the zombie dies, but that doesn't fix the floating behavior that affects both mobs. Any assistance from any one would be cool, thanks 💪😎👍
