Reinforcement beacons do not deploy correctly when the unit is killed whilst placing it.

[-H3X-]

If the player kills a Corpus unit that is placing a beacon the animation for the deployment is interrupted, however this causes the beacon to never render as an object that can be interacted with or destroyed. The map will display the icon for a reinforcement beacon although the model never renders, and cannot be hit or removed. This causes the alert level to rise with no possibility of preventing it as a result. This issue can occur 100% of the time provided the user kills the unit placing the beacon fast enough. 

1. Enter Orb Vallis
2. Locate Corpus enemies
3. Attack enemies until they attempt to summon reinforcement
4. Kill the unit whilst it is placing the reinforcement beacon
