Unexpected Disconnections and Client Crashes When Playing Together

Hello,

We would like to report a recurring issue that has been significantly affecting our gameplay experience.

One of my friends has already submitted a ticket regarding frequent "Unexpected Disconnection" errors. When this happens, the entire instance is destroyed, the map becomes inaccessible, and all progress made within the instance is lost, including any loot that had dropped.

In addition to the disconnection issue, he also experiences full game client crashes. These crashes do not always destroy the instance, but they can still result in character deaths if they occur during combat.

What makes this particularly strange is the following:

- When I play solo, I do not experience either of these issues.

- However, when I create an instance and my friend joins my party, the problem starts occurring on my side as well.

- In these situations, my game client frequently crashes, and in some cases both of us simultaneously receive an Unexpected Disconnection error, causing the instance to be lost and all progress within it to disappear.

- When the roles are reversed and I join an instance created by my friend, the issues occur even more frequently—essentially at the same rate as when he plays alone.

This behavior makes it appear as though the problem is somehow tied to his connection, character, account, or client state, and that it may affect other party members once they join the same instance.

System Specifications

Affected Friend

CPU: AMD Ryzen 7 9800X3D
GPU: NVIDIA RTX 4070 Ti
RAM: 32 GB

My System

CPU: AMD Ryzen 7 7800X3D
GPU: AMD Radeon RX 7900 GRE
RAM: 64 GB

Both systems are fully updated with current drivers and operating system updates installed.

My friend has also created a detailed forum thread describing the issue and listing all troubleshooting steps and fixes that have already been attempted:

Beyond the technical issues themselves, this has also resulted in the loss of a significant amount of valuable loot and currency. Due to instances being destroyed by the Unexpected Disconnection errors, we have lost multiple high-value drops, including Omens of Light, Divine Orbs, and other rare currency items that were either dropped during the affected runs or became inaccessible when the instance was lost.

As a result, this issue is not only frustrating from a gameplay perspective, but has also caused a meaningful loss of in-game progression and wealth over time

Thank you for your assistance.
