Summary: 

In HTTYD, using a dragon's attack while moving causes the dragon to spin rapidly.

Impact:

This issue makes dragon combat significantly difficult and frustrating. If you are moving, your dragon will often shoot in the opposite direction it is facing. 

Repro Steps:

1. Enter the HTTYD world.
2. Enable cheats and change gamemode to creative.
3. I have attached a video demonstrating how to spawn a wild dragon and tame it to aid with this step. Run `/summon aurora:monstrousnightmare ~~~ wild`, grab the "meat" item from the creative inventory. Feed meat to the dragon until it emits hearts. Interact with the dragon to ride it, the dragon will buck you a couple times, repeat the riding until the dragon accepts you. 
4. Tap the space bar to begin flying and look upwards to ascend. 
5. Punching will attack. Observe dragon behavior while flying forwards and attacking.

Observed Results:

The dragon will spin rapidly and all forward momentum will be lost.

Expected Results:

The dragon should send their projectiles forwards without spinning or otherwise interrupting their forward flight.

Notes:

The dragon behavior systems are quite complex, the attack system is especially so. I would be happy to answer questions to help understanding and to identify the point of failure.
