Why maintenance when clan war is going on?

Why Crossout planned maintenance when there is clan war going on?
They cloud wait 1:15 t it was over and do there work when there is now clan war just between the 2 sessions
So Crossout why???

obviously there was a game breaking bug. its the only time they pull servers down at this time of day.

Like Pending said, it must be cereal serious for them to do this especially right after a BP update
