Can confirm, too.

Not a single challenge counted since reset although there were more than enough reasons to.

The mask could be interesting for a backfire build.

One attribute HZP, two mods against bleed would mean up to 30 % against the bleed effect.

@ubi-nacho Hi,

I added it as a comment in the linked site.

I hope, it will ensure us a scientific breakthrough.

Hi @ubi-milky and thanks for the answer.

To answer the questions ...

... in short: On the next day the game worked without problems.

... in a more detailed way:
On the day with the problems I loaded character 1 and was in the Summit (Lobby). From there I could not fasttravel to any other location,
the loading screen showed up, but the loading stopped at 9 % and after a while the delta-error came. With this character I could
only enter the Summit levels through the elevator.
The other characters 2, 3 and 4 could not be loaded. The loading screen showed 0 % without any change and after a while the
delta-error came.
After restarting the computer 2 times, validating the installed datas and intense swearing this behaviour was reproducable.
So I gave up and played with character 1 in the Summit the levels 1 to 10 completely. After that I could fasttravel with character 1
to other places (first edit in posting #1). Unfortunately I found out, that the other characters were not usable in the described way
(second edit).

To the DZ-related question: It's been several weeks, that I visited DZs, so the influence of DZ, checkpoints and contaminated loot
should not exist.

To the question after disconnection: There were several disconnects over the last weeks before (but it is better now, thx!), almost
every day - mostly CTDs after freezing. But I can say for sure, that I played the evening before without ending the session with an
error. I played and ended normally.

Speculation: On the day before I reloaded level 10 of the Summit several times in short order to get a room like this under point 3.
Maybe this got something to do with the problems.

Hi there,

I can't leave the Summit or start one of the other characters, who are somewhere other than in the Summit.

When I try to leave the Summit or start one of the other characters, I get a Delta-01 error.
In the Summit the game seems to work correctly, it is possible to use the chatbox, doing inventory management or
go to a level.

I restarted the computer and checked the installed data, but the Delta-01 errors prevent me from playing.

Any suggestions?

EDIT: After some hours, a Delta-03 and doing a boss level in the Summit, the game behaves like it should and allows travelling.

EDIT 2.0: It is completly crazy. Only one character can be started and used. The three others do not load and the attempts lead
to an Delta-01 error.
The one, which I used in the Summit, works and it was possible, to do the Tombs (for the manhunt and the Daily Premium Mission).

Do I have to explain, how annoying this is, or is it self-explanatory?
(During the one mission I played, other agents went offline. At least I'm not the only one in troubles.)

Can someone else repeat this experiment? Ensure you're running Demolitionist and have one China Light piece and the frag grenade.

I did the same yesterday with the same results.

I used an explosive build (3 Empress, 2 Grupo Sombra, 1 China). With a fragment grenade I killed three of the four True Sons and the counter
did not count. After the death of the fourth True Son (MG dude) it counted one up. Parallel to that the weekly challenge counted one up.
With using the concussion grenade all four were killed and both counters (Global event and weekly challenge) counted 4.

I did this event more than one time, but this is the first time I experienced this. Maybe the weekly challenge interferes somehow.

@dagrommit I did another run and resetted before reaching the train, and the next run I had no problems.
Maybe the bug occurs only on resettings after the train.

@dagrommit Straight after another run. I did not play the run before to the end, but restarted it just before reaching the named machinegunner Raven.

In the run, in which the bug occured, the train stood there with open doors and after killing the last enemy the game demands to secure the area.
Like I said, I checked with pulse scanner and I'm pretty sure, that I killed the whole patrol.

@dagrommit To answer the question: Yes.

My run before (solo) was fine, but then in the next try I got stuck (under 13 minutes, could have been interesting).

@opaitaon1 I experienced the bug 5 minutes ago.

There are no surviving enemies, I checked this with pulse scanner.

I read some suggestions, that restarting the mission is not enough and that it is a good idea to travel back to DC
and then retry.
I'll try that.

Edit: ... and btw: The train is standing there, although he normally first would have to arrive.
Before this run I had another run.
