ACF7: Fix possible Lua error spam in intro sequence This was caused by a race of onGearDelete vs AnimationSetup. If AnimationSetup came first, it uses old values from the natives table. The solution is to force the code to guarantee that AnimationSetup always coms after deleting gears in the natives table.
