@Sooxzay they ran out of assets. In the Dev video, they said they had to take away assets elsewhere to add in the FOBs in B sector.
So I thought it would be a good idea to delete the entire car tunnel that never gets used. Just seal the entrances off with rubble, make the elevators inop and use all those assets to add cover in the untouched areas.
However, this map is done. They have made the changes to the map, and they are not coming back to this map again, unfortunately.
We will likely only see 4 maps edited, one per season.
Once S4 is done, they won't be updating any additional maps, and they surely won't be hitting edited ones a second time like Kaleideoscope.
