The issue is identified. Unfortunately the fix didn't make it into the last update - but hopefully next one

The base game Marshall variant does not support those textures. We can't edit that model, so there is nothing we can do about this.

Just redownloaded compatibility data, and now it works fine. Looks like the problem really was with Steam.

Can't say for sure -- I didn't check compatibility data with the game (since I have bought DLC), only with Arma 3 server.

It's for sure a Steam issue, since I just booted up the game with only the compatibility data active and everything worked fine.

Did so, as well as redownloaded compatibility data a few times and compared sizes with bought DLC -- they were the same. As a workaround I uploaded to my server bought DLC.

Verify integrity of game files. Compatibility data mod files are exactly the same as the dlc build.

OBS is a heavyweight app that is mainly used for live streaming. I don't need such app, I just need a lightweight app for taking screenshots and short videos, which is what Bandicam successfully does.

Bandicam is still a thing? *2004 flashbacks
Just use OBS ...

Fixed with next patch.

Shouldn't be medical tents. Fixed with next patch.

Fixed with next patch.

How do I move this bug report from the Western Sahara DLC to the Spearhead DLC? It's got the wrong DLC tagged.

workaround is functional, just a little frustrating without auto-save between scenarios especially if it glitches on one of the last scenarios to complete since each scenario takes a fair amount of time

Confirm.
@Major.Heretic, as a workaround restart the showcase and complete this submission first.

Scenario is actually 5th from the left*
Saving - exiting - resuming scenario also seems to have no positive effect
