I have recently been working on a project that requires both WEST and CIV sides and I need to display groupChat messages for information. When I ran <player groupChat "Testing";> on the West player, the message was displayed but when I passed the exact same command on a civilian player, the message did not display. I tried running <hint "Testing";> on the civilian player after <player groupChat "Testing";> and the hint showed up just fine but the chat message did not show. I thought it may have been a mistake in my scripting so I created a blank mission with one playable WEST unit and one playable CIVILIAN player. I put the init.sqf in the mission folder with one line of code, <player groupChat "Testing";>. I then copied and pasted the mission to my MPMissions folder and started a multiplayer match, first playing as the WEST character. As soon as the map started, I saw the message in the chat, "Testing". Then I tried again with the CIVILIAN character and nothing showed up. The same script ran on both so there is a problem with the CIVILIAN side and groupChat. I also tried with globalChat and that did not display as well.

Thank you for your time and I hope this will be resolved soon, as for the meantime, I will overstep the chat commands and use an alternative.
