Alpine Unrest crash on mission with the cave system

Platform: PC

Description:

The mission where you have to explore the caves up the wooden stairs by the north east (?) coast (I will get coords later) of the Alpine Unrest island, guarded by a Tank and a couple of runners.

I have completed clearing the tics out and exploring the cave system just through general exploring, before getting this mission.

On getting the mission, defeating the guards and entering the cave, I see the first tic. On trying to shoot it there is no effect (tic does not die / move) and then the game crashed.

Steps To Reproduce:

Unknown. After spending over 100 .50 FMJ rounds from a ‘good’ level .50 cal gun and a fair bit of time, I have not been so interested in opening the game again so far.

Host or Client: Host

Players in your game: Cave originally cleared in multiplayer but the other players dropped off and then I got the mission and encountered the problems entering the cave alone again.

Specifications: i7-7800X, 24gb Ram, NVME SSD x2 (Os / Game), GTX 1080Ti

I have now completed this (went through the back door).

Maybe it was completing before the mission was obtained and then trying to complete after getting the mission in the same session (ie. no game restart).
