Last game a Jester shot down a flying transport. I don't believe this is supposed to happen.
The transport was landed on the ground and the Jester began to attack it. After the attack started, I ordered the transport to take off and fly home. The Jester continued to attack it, chased it and eventually shot it down. Replay attached.
Jester attacks 8 o'clock island at 7:44, begins to engage the transport around 8:00.
