Guild Wars 2

I accidentally found a potential exploit in snowball mayhem that lets you get under the map, how do I report it? Also I won’t get banned if I report this will I?

You won’t get banned, it is just a bug not an exploit, you are unable to do anything by it, you just go underground in the water where you can not use any skills, nor deliver or get new gifts,

yeah, ive been seeing this off and on thru out all of wintersday, ive gotten stuck 3 times myself
