Summary0005771: DUKE system does not work on dedicated server
DescriptionThe DUKE system used on a select number of RHSUSAF vehicles does not work on a dedicated server. This appears to be due to the use of enableSimulationGlobal in the duke_jammer function.

The DUKE system appears to work in singleplayer and when the player is the host of a local multiplayer server (non-dedicated). This makes sense since the player would be the server in both of these cases, where enableSimulationGlobal is sufficient.

A suggested fix is to update the duke_jammer function to remoteExec the enableSimulationGlobal command on the server. I'm uncertain if this is the most performance friendly option, but the main loop of the duke_jammer only runs every 0.5 seconds so it may be acceptable.
Steps To Reproduce1. Load up the duke_test_vanilla_MP mission on a dedicated server. (Make sure you are logged in as admin)

2. Start the mission and place a Large IED.

3. Get into the MRAP and enable the DUKE system. Confirm that it says DUKE online.

4. Scroll and touch-off the IED you placed. Notice how it explodes and that the DUKE system did not prevent it from exploding.

In the mission I've provided, I have made a variant of the duke_jammer function that uses remoteExec for the enableSimulationGlobal command. To see how this results in the intended behavior do the following:

1. Restart or reload the mission.

2. Place down a large IED.

3. Get into the MRAP.

4. Use the debug console to locally run the duke_test_2.sqf script included with the mission. (execVM "duke_test_2.sqf") Notice that the systemchat shows that simulation has been disabled for the IED.

5. Scroll wheel and attempt to touch-off the IED. Notice that the IED does not explode.

6. Drive approximately 50 meters away. Notice how the IED then explodes, as intended.

https://community.bistudio.com/wiki/enableSimulationGlobal [^] It's suggested to run it only on server so I guess that's the only correct way anyway. enableSimulationGlobal is only launched once per ied detection so it shouldn't cause too much problems. If you have a chance, please try it with couple people and let me know if it's somewhat problematic. Thanks for the tip - it should be hopefully resolved in next patch.
