Yesterday's update brought ability to see money zones and CEO zones for players in gang. However, they can't participate in these activites when in gang war over a gang hood. But if they are for example in CEO zon and start shooting, they might start attacking gang hood and that will disable them to participate in that CEO challenge.
Therefore it will be neccessary to change the way how to attack gang hoods. There are two options:
1. Through interaction menu - Gang - Attack gang hood 2. By killing NPC gang members on the hood - this will be like in singleplayer, however it might be sometimes time consuming to find the NPCs in the hood.
Command /attack will of course remain, but that is not primary way how to attack gang hoods. Vote for the option you like more.
