"Leaving the mission area" while freeroaming a specific location.

[Grátur Guð]

I've completed the main story and now every time I get close to the sunken area where the sunken airdrops are I get the "leaving the mission area" msg that insta-kills me. If I choose to respawn afterwards the game spawns me at the renegades hq like if I was still doing the epilogue quest.
Is there any fix? I'm basically soft-locked from getting any high-tier end-game loot...

i didnt have this problem while having the sunken city unlocked until the most recent update and now I spawn inside the renegade hq and have the leaving mission area now... :( ( only way to fix the timer is respawn at last story point and you can explore the area after, but you have to do this every time u restart ur game.

I have the same issue. Quitting the game sometimes helps..

PARTIAL SOLUTION:
It seems like quitting the game doesen't help. BUT: Only certain area of the Sunken City triggers this countdown.
* DON'T go near the military air drop which is NEAREST to the Colonel's place in New Found Lost Lands-area.
* You CAN loot everything else but that last one. And do a counterclockwise route, so you won't enter in the proximity of the New Found Lost Lands.
* The most eastern air drop needs to be carefully approached from south, so you won't enter to the area which triggers the "leaving mission area"-bug.

For me also there is enemies on Colonel's place, which weren't there before...

Too bad I can't attach a image, I kind of figured out the "trigger zone". But for now the text based guide have to suffice.

I have the same trouble. As Temetus described, it's 3 specific air drops I can't gain access to due to the randomly shaped trigger zone around that area.. No fix found at this stage so I'm just waiting for it to be patched.
