Guild Wars 2

Hey guys, I noticed a fun little bug, with minis, They somehow seem to be able to take some kind of damage(unknown how & what), and they get lower health the longer they stay alive. So far I only know this is happening in WvW. Also only tested on one mini (Liadri the concealing dark)

My record is around 65% health on mini, and that is around ~2h raiding(1 hour 30 min fights, no deaths)

A screen shows the issue more exact.
