spyro 3 year of the dragon, problem with Agen 9's lab

There is a small bug i have no idea how to un trigger, i am missing exactly two gems short of having all of the avaible 700 in the stage, the problem is that the gem refuses to spawn at all, i checked up and down the damn place and no gem, any one has faced a similar glitch?Also it's consistent, using the press all R and L buttons ability of sparx tells me there are no more gems in the stage, so i am wondering if any one has faced such a glitch and has been able to bypass itPS i am using the greatest hits version.

As I said on MSN, I doubt its a glitch. Sparx treasure finding is notoriously unreliable and its well known to say it cant find any. the gems are likely hidden on an out of the way ledge or something.

I'll try again in a few days, i grew a bit frustrated but sparx treasure finding only ha failed me twice, fire works factory AND Agent 9 lab, otherwise i tend to find all gems.
