HUGE MAP BUG : Portal disappearing as i'm opening a map and equals failure

Just happened right now, I opened a map while at my hideout and no portal appeared. I left game and when I came back the map was "failed"

It happened while exactly at the same time i opened it, a player entered my hideout.

This is inacceptable, it cuts my way into the atlas and f*** me up and as usual nothing will be done before months so yep great !
