I’m playing Diablo IV on PlayStation 5 Pro. My character is a Rogue on the Eternal Realm.
I’ve found a serious bug that happens after joining another player’s party.
When I’m playing solo, I test my damage in The Training Grounds, and my damage reaches multiple trillions, which is the expected value for my build.
However, after I join a party, even if I test on the same training dummy, my damage drops dramatically to around 100 billion at most. Nothing about my gear, Paragon, skills, or build has changed. Only joining a party triggers the issue.
Sometimes closing the game completely and restarting fixes it, but this is random. In about 90% of cases, restarting does not solve the problem.
The same issue also happens in The Pit (Tier 125).
When the bug occurs:
-
Enemies barely take damage.
-
Sometimes dying once temporarily fixes it, but most of the time it does not.
-
Under normal conditions, I can reach the Pit boss in less than 5 minutes out of the 14-minute timer.
-
When the bug is active, I can still reach the boss, but the boss’s health eventually stops decreasing completely. No matter how long I attack, the HP bar stays almost frozen until the timer expires.
This appears to be a severe damage calculation or multiplayer synchronization bug that only occurs after joining a party.
