Hello.
Sorry for the delay in responding.
I had already given up on this bug.
I thought that with this new major update, the bug would be fixed, but it wasn’t.
I’ve already tried:
Repairing the client.
Uninstalling and reinstalling.
Opening the game on my phone.
Changing the resolution.
Changing the graphics quality.
Using skills that can pass through walls: teleport, jump, etc.
It’s impossible to leave the mission and resume it later, even though many people told me it was possible.
You can only do that in secondary missions, not in the main one.
I wrote to official support and they redirected me to the forum, telling me to wait for responses from the community.
Which never came.
I was hoping that in the last update they would fix the problem, but they didn’t.
Now they supposedly say that in the next update on April 2nd, they will fix some issues.
Hopefully, they’ll fix ours.
I can’t kill Diablo either.
But if you get invited to a party, then you’ll be able to do it.
