The Rise and Fall of Gentlemen (Hildibrand Quests)

hi,

after checking mi journal ( quest undone and done ) i found out that i am unable to continue the quest chain line of the " Hildibrand Quests" i did the chain on the previous patch and for some reason those quest disappear of mi journal has done, i tried and and teleported to the location of each npcs for each part of the quest line to see if i didn't forgot something,i even return to ulda to check in case the quest line reset itself or something but after searching, i am unable to continue the quest or even restart it, the nps just do not have any quest for me to make me able to continue the chain line, i don't even see those quest undone or done in mi journal anymore so i cant continue the quest line aswel, i am stuck and so cannot finish this chain to be able to open the extra contents.

could you please try to reset this chain line for me, so i am at lest able to restart the chain and so on will be able to flow the next part of it please .

i thank you in advance for your consideration
