Don't know if you still have this issue but they came with a fix for me. In your server.cfg (admin folder) set the difficulty to custom.
Then in your Amin/Users/Admin replace everything in your Admin.Arma3Profile file with this:
version=2;
viewDistance=3000;
preferredObjectViewDistance=3000;
terrainGrid=12.5;
activeKeys[]=
{
};
difficulty="Custom";
class DifficultyPresets
{
class CustomDifficulty
{
class Options
{
autoReport=0;
cameraShake=1;
commands=1;
deathMessages=0;
detectedMines=0;
enemyTags=0;
friendlyTags=0;
groupIndicators=2;
mapContent=0;
multipleSaves=0;
reducedDamage=0;
scoreTable=1;
staminaBar=1;
stanceIndicator=1;
thirdPersonView=1;
visionAid=0;
vonID=1;
waypoints=1;
weaponCrosshair=1;
weaponInfo=0;
};
aiLevelPreset=2;
};
class CustomAILevel
{
skillAI=1;
precisionAI=0;
};
};
Save everything and you should be able to change the difficulty to your liking.
Saving your settings on the control panel will fuck everything up again. So if you press the green save and restart button on your panel you will have to do it all again.
Hope this helps,
