Dajkah Inlet (Challenge Mission) bugged??

Currently i am trying to play Nightfall with a 2nd char through the game (monk)... atm i am trying to do Dajkah Inlet (Challenge Mission). I have done this mission before with my ranger (i have all ascendend armors there).

But now with my monk several doors stay closed while they opened while i played that mission with my ranger...

In the 2nd level i have to kill both guild lords before i can move on to the 3rd level (portal isnt working after beating 1st guild lord in 2nd level). And in the 3rd level i cant continue at all (i cant try much due the timelimit).

I know there was an update on 22 november but all it says is: fixed several bugs, so i have no clue what those "bugs" were and what has been "fixed"

Wiki isnt mentioning much about this mission...

Does anyone know what is going on??

For the 2nd island, only the eastmost lord needs to be killed to activate the portal. I believe it's also the same for the third island. Killing the other one still gives you the time bonus, though.

With my ranger i always killed the "east guildlord" and that triggered the portal... but to reach that guildlord you have to enter a door and go over a bridge (carpet). Sadly that doors stays closed and only opens when i kill the "west guildlord". I didnt had that problem when i played there with my ranger

Dajkah inlet has always been like that. Especially for the 2nd level, you must kill the west guildlord first to even gain access to the east guildlord. i have done this mission multiple times and i've found this to always stay constant.

besides, its good to kill as many guildlords as possible, since you will get more sunspear armors

Like i said before it hasn't always been like that... i think i have done this challenge apx 40 times before (for myself and while helping a guildy) and i was always able to kill the east guildlord on the 2nd level without having to kill the west guildlord first.
