Guild Wars 2

First: I do not know how to repeat this. It has only happened once in the 3 years I’ve been playing.

I was doing a gathering run, and just killing random mobs. Not a boss or world boss event.
I had just finished killing a critter with my pet, while gathering a node with my character.
Among the loot received icons floating down on the right side of my screen, I saw a blue diamond and “303” below it.
I happen to know, for sure, that at that time, I had exactly 303 gems in my account.
No additional gems were given to me, and I didn’t expect them to. As far as I know, gems aren’t ever given as loot, but it struck me as odd that this item showed up at all in the loot list.
Was this something that popped up instead of me receiving something else extremely rare? I don’t know. But something was looted that clearly showed up incorrectly and resulted in a non-loot item. It was more of a reminder that i had 303 gems.

Did you have 303 gems before that happened, or you noticed that amount after it happened? No idea what it could be as I have never seen gems being rewarded that way. The only time I have seen the game rewarding gems was through that AP chests but that’s after opening them, not when acquiring them. Really odd. Any screenshoot?
