Dear devs, any word on that?

Either fix this bug or remove the “win 5 co-op battles” from the quest tasks for as long as it takes to fix the party mode. Please.

I tried around 20-ish party battles with other players this week. 1 (say: one) was successful.

It can’t go on like this.

Hey just an update on the RE- and CE- errors that occur during party battles:

The devs have pinpointed a couple of the main reasons for these errors and are working on a fix now. We’re hopeful this will resolve most cases of these errors occurring.

When we have an ETA for the fix we will include it in the Known Issues article in the Help Center and let you know on the forum.
