Edit II: When doing the "Sporocyst Assult" secret mission in the center of the Ecro map (to be unlocked from both sides, Iunlocked it from the north) I consistently get a blue screen on PS4 (3 trials) immediately after loading screen finishes. I tried that type of map/enemy on ebony crusade and this one works well. So its not related to the map/enemy type in general. Also I noticed from the preview window that the secret map and the supreme mission at the upper right appear 100% identical? The map preview looks 100% the same, so you used the same map twice in one void crusade?!

Thanks for the quick reply. Overall I enjoyed the new Ecru map, good mob density, lots of (relic) chests, and even a bit challenging if you end it like a 111-113 final mission :) Mechs are beast enemies, their incredibly high firing rate  at high map levels is a welcome challenge, that even made my psyker sweat a little bit.

When starting the first Ecru I had no other void crusade running before and game was started frsh after patch. The only thing that comes to my mind is my psyker did not drop the ecru shards but my other toons and he just got them during by storage. Later he dropped shards himself so that might have changed it, anyway it works now.

About the layout: "Little similar" is a bit of an understatement, but you are right there is a minor change in the outline of the map it you look at it carefully. Since I could not launch it but only see the map layout I cannot comment on the interior so far ;-)

Just to avoid a missunderstanding: With "works now" I mean I could launch several Ecru missions meanwhile. The crash to the specific mission in the center is still there.
