Guild Wars 2

I doubt this will get read, but the Toolbelt skill of the Throw Mine ability doesn’t function properly since the patch.
What I mean by this is:

1. It does not detonate when walked over by an enemy.
2. The cooldown resets to the full, base cooldown when walked over at all.
3. The screen shakes for whoever’s walking over the Mine Field.

Bug doesn’t appear to happen in s/t pvp areas
as OP said if you don’t detonate within about 10 seconds of using
Engineer skill [Minefield] The skill is set in an infinite loop.
