darkSpyro

it’s been a while.
on my absurd quest to 100% every mainline Spyro game, I’m about 70-80% done with enter the dragonfly. I figured out my old DS account info so I figured why not try and see if anyone can help me with what appears to be a softlock.
trying to get the last dragonfly in crop circle country- the one with the four cannons? when I got to the third the ufo wasn’t hit by the cannon, and I am unable to reshoot the cannons as it appears to have been a one time thing? I trudged on to the fourth thinking maybe it was just a visual glitch only to see that hunter was not there, and when I shot the cannon, the UFO had completely disappeared out of the sky. I went back to the third cannon, it was gone there too.
I restarted the level, restarted the game, to no avail. does anyone know how I could possibly get around this? It would be awful to have to replay this broken game again when I’ve gotten farther then I ever have lol.
TIA

If I did, would I be able to transfer my saves over? I believe im playing on an original GameCube version.
