Believe I see the issue now. On Experimental the setting in gamplay is "Mouse vehicle control", while one stable, the setting is "Mouse aircraft control". Were the settings merged? Cannot freelook while driving Humvee with mouse vehicle control without using ALT.

It is a milsim. Players on controller can not so easily drag and drop from inventory to inventory.

This is emberassing, I tried that over and over. Now after a few relaunches, it just works.

Realistically, players should not be able to drive up to a sign and drag full supply stack or any inventory into vehicle instantly. Getting out and going to the back of the truck to load and unload should be forced, as console users cannot do the same as PC without extra steps.

Is there a reason that I am able to play on Stable servers through Experimental game, or is this the desired effect?
