China Assault Troop Crawler can become a firing ghost unit after Reinforcement Pad drop

[xezon]

China Assault Troop Crawler can become a firing ghost unit after Reinforcement Pad drop.

Repro:

• Capture the Reinforcement Pad as China Infantry General
• Kill the Reinforcement Pad while Reinforcement Plane is approaching (?)

This probably is a code issue.

This bug occured during a game in twilight flame.

Not sure if this invincible/invisible unit bug has been observed before.
But on Twilight Flame this reinforcement pad was captured by pink at 4:36 and 5 minutes later when it gets destroyed it spawned an invincible/invisible troop crawler. Moreover the reinforcement pad never dropped a troop crawler in the first place, they have a 2min cooldown.

The second part of the reproduction is incorrect.

Repro:
Capture the Reinforcement Pad as China Infantry General
Kill the Reinforcement Pad while Reinforcement Plane is approaching (?)

The correct reproduction step is to destroy the reinforcement plane before destroying the reinforcement platform itself.

Note: the minigunners only start shooting when the player in control of the minigunners has vision of the area.

This is a bug where units are added to an already dead container; TransportContain::createPayload -> OpenContain::addToContain. The units are invisible, indestructible and hover above the pad, and attack any nearby enemies but cannot be selected. For the video I changed the code to make the drawables visible.

Reproduction is simpler than previously mentioned:

1. Capture the Reinforcement Pad as China Infantry General.
2. Destroy Reinforcement Plane before the drop happens.
3. Typically the infantry will spawn above the pad.
