Maven Atlas invitation disappeared

I completed to kill 10 Boss Map observed by Maven, i received Maven invitation Atlas for Kirac, i ask to open the map, i takes long time but it's open.
I enter the first portal and then during the load i'm disconnected of the game.
I reconnect immediately, and what my surprise : the portals have disappeared, no more Maven Atlas invitation from Kirac and the count of Boss killed observed by Maven restart to 0.
So much hours of game just vanished for nothing.

Can you repair this ?

Thank a lot in advance.

Its an instance crash and nothing can be done sadly. A report does get sent to GGG automatically if it makes you feel better.
