Possible Gamebreaking Bug found

Today in EU all servers are horrible - on every loading screen you have to get a coffee and wait 5 min. sometimes you wont get ported to the location because of realmserver not active and so on.

now i wanted to do my daily minor vision - after clicking the portal i got a loading screen - 2 minutes later i got a disconnect while loading screen. presst ALT + F4 and tried to login again - my character was already in the vision and i had 100% sanity. now i played the vision normal als every day. after i died i always waited to get rezzed by a random nobody came to me so i decided to leave the vision. everything like every day but when i got the loading screen, i got disconnect again. now i just pressed ALT + F4 and reentered game - my character was again in the vision - i had 0% sanity but i can move. i tried to kill some mobs but every initial got dmg and then they escaped. BUUUUT there are other players so i just ran with others and killed there mobs - i couldnt get aggro but i could do dmg and they didnt escaped. so i did this a while - after around 1000 coalescing visions there was no other player left in the vision so i decided to leave also but how? i didnt know there was a portal to get out :P i tried to use the items which gives +50 sanity and then killed again some mobs (yeah i could kill them because i had sanity +lol+) after the sanity was again at 0% i didnt died. so i tried to use my hearthstone - saw that i should work but then realised the portal and clicked it - it portet me out of vision and so i could play the rest of dailies :P

probably there are mechanics to stay in vision with disconnecting, etc. hopefully anybody can find something to exploit this - so everyone could farm infinite coalescing visions
