Hypervelocity Cannon on Yavin 4

[yutpaeksi]

The first time I fire the cannon, it takes a really long time for the projectile to emerge and for it to hit. Much longer than in other battles elsewhere. Subsequent attempts to fire the cannon (the timer resets, the audio FX "Hypervelocity cannon firing" triggers) but no projectile ever appears and my target is undamaged. I fired it 5 times on Niriz, and he still has full health. I watched him and the projectile just never emerged.

Has anyone else encountered this oddity?

EDIT: Actually what I think is happening is that the late emergence of the HVC projectile is causing it to miss wildly. I Just saw it but it was nowhere near the target (capital ship).
