Team Arena's Overload gametype has red and blue team Obelisk base
objects. It uses separate entities for visual and damage. Only the
damageable entity was dropped to floor. Leaving model floating off
the ground.
Team Arena's Harvester base has the same problem. Model entity
floats in air but trigger entity drops to floor.
Drop all Team Arena team base models to floor. Fixes CTF, 1Flag,
Overload, and Harvester base models.
