An unexpected disconnection occurred

Hi GGG,

I am having issue in last 2 hours. There is "An unexpected disconnection occurred" problem occurs while in map. The game will force out to the login title page when it occurs. After relogin, the portals of map will gone. So far, it occurred 3 times in my recent 4 maps. It is unplayable.

I just switch to flicker strike. I am not sure if it is a flicker strike problem.

Edit 1:
The problem is fixed by changing the network mode to "Predictive"

Edit 2:
Just encountered the problem again even with "Predictive" mode

Edit 3:
I tested for many times. I think there is a bug between Flicker Strike and Harbinger. Everytime I interact with Harbinger using Flicker. There is a chance to crash the game and show "An unexpected disconnection occurred" and all portals will be gone. GGG, please fix.

My friend is experiencing same issue.

And I found old post https://www.pathofexile.com/forum/view-thread/3505409 I think it's actual an issue.

Harbinger + Flicker strike sometimes crashes the map and can't access to that map anymore and also all loots from that map are gone.

Same problem

Harbinger + Flicker strike = crush map

Soooooo sad =( im love Harbinger. but cant farming
