Map Boss Exit Bug

There is currently a bug that prevents you from exiting the map boss' arena even after defeating the boss. This bug appeared after the recent 0.4.0i patch.

https://imgur.com/a/MRnSLGy from the "objectives" tab, the map is complete (map boss is defeated) but there is still a red wall that prevents you from exiting the arena which usually stays on while you're fighting the boss and goes away after you defeat it. But in this case the wall never goes away, the bug is not map specific, happened to me on many different maps and made me miss out on a lot currency and items.

And no, travelling to the hideout and coming back does not fix it.
