It's still present in current dev branch (1.31.127272).

I have the same problem in the mission "Supply Network".
I don't mind my stuff missing, but I don't get my explosive charges required for the mission!!!

I'm using the Dev version (1.21.124754) without mods.
Although I'm using the profiles parameter, I don't think it should be relevant.

I made a video about my problem. Notice my backpack missing with the charges that are required for the mission.
Also, I cannot select a backpack and the charges from the mission briefing inventory.

(POSSIBLE SPOILERS!!!)

Just checked the mission taking the default loadout from the armory guy.
Explosive charges are still missing with the backpack. :-(

The problem is present in the dev branch (1.31.127225) and also in stable (1.28.127008). No mods used.
The view stays in the center of the head, but does not follow it's direction.

An easy way to reproduce the issue is to place an explosive charge a few meters ahead of you and touch off the bomb while facing towards it. You can also quickly switch between 3rd and 1st person view while ragdolling to see the actual direction of the head. You can slow down the time for the time being with a setacctime in a simple trigger to see the issue better.

The rotation of the camera is also missing when ragdolling in 1st person view.

It's sad to see this issue unnoticed. :-(
