Today I had a similar issue.
I was swimming in a group of 5 people from prison island to the coast.
10 seconds into swimming there were some status messages. I thought these were the standard messages like, i am damped etc. Then i realized a red message saying: i am drowning. I think it repeated 10 times. Tried to swim back to the island. After that got two shocks and i died. I think the moment before the red message appeared there were also a message like "i cant breath" or something, not sure.
My char was healthy, hydrated and energized. I was definitely not shot. The four other guys made it to the coast. One hour before that i swam from the coast to the island without any problem.

The same here. After the maintenence one week ago, i was at prison island. There was loot everywhere. Good stuff, weapons, optics, attachements, magazines, plenty ammo. It was all gone by the weekend. Now one week later there is nothing of value anywhere. The same happened to the camp at NW airfield. I lootet there for 3 days. Nothing is respawning, maybe some ammo and food, dont know. But beside of that nothing.
