Guild Wars 2

I just had the luck of getting a modrem heart dropped. So I went to the Cryptobotanist at Camp Resolve and checked how much it would get me: 100 Bandit Crests according to him. I exchanged it and all of a sudden my picked-up-list showed multiple hundreds of Bandit Crests. Checking the inventory showed, that I had gained 10.000 Bandit Crests.

There are at least 2 other threads already mentioning this issue.
