I am having the exact same problem. I guess i should not have exited the game last night when i was finished with the level before that. Apparantly if you log off or maybe other things as well you can't get into the Monolith.

I hope the dev's are working on this issue as it is a big one for a lot of people including the both of us.

Please help WOLCEN DEVS!!!!

Same problem here.. game crashed , now cant do anything on this quest.. christ

Same, this is very sad a transition bug blocking game progress still happening after release, can't wait to finish the game story and uninstall it

After 8 times of exiting and restarting the game i was able to get in... you might want to give it a try. not sure if it will work but ya never know.

I finished Act 3 just now and the ending is buggy as hell as well. I was invisible for the last part... don't know how. All you could see was my sword..

other parts after that were buggy as well. They have alot of work to do.. So far i am mostly happy with the gameplay but just too many bugs...

I have a possible work around. Enter your game in normal -> public mode with someone else joined in. I managed to finally enter the monolith this way.

no need quit the game just offline/online, So disconnect/reconnect and retry to enter the monolith gate
