- Map object num was incorrectly copypasted onto the Dead Line Ring Vaccuum as well - Was getting destroyed instantly because its first spawnpoint is a deathpit. Now it only kills itself when it lands on a deathpit, not if it started on one - Use destscale instead of scaling every frame - Reduce duplicate P_IsObjectOnGround calls - Now has its own state
