Guild Wars 2

When i gathering in Orr, i’m always use the Orichalcum’s tools.
But sometimes when i garhering, I have a high probability to get the garbage.
Is this correct the situation?

P.S. I have notice that if i get the garbage, it’s usually happened when i in-fighting and gathering in the same time.

I noticed this too lately. Kind of weird… but it is not specific to being in combat. I do think it is a bug (or feature?). Once it happened to me twice in a row. I swapped it out and re-equipped and it started to work again.
